I'll be honest which is that many of us don't discover the LOR requirements until after we receive our secondary. It's not conveniently listed for us on the MSAR. If you live on the West Coast like I do and have to apply to 25+ schools then you really don't keep track anymore since if you do have the 2 science + 1 non-science it meets all the minimum requirements and you just send the same packet everywhere. That is why people have been hesitant to list schools. It's not that they're not sure but because it takes a little bit more effort to actually go back and look at the school requirements.
However, since you don't seem to want to take our word for this, I've looked over the list of medical schools I applied to and found a few. Keep in mind, I decided to stop after I felt there was a sizeable quantity and not because this is actually all the medical schools that require 2 science letters. Although you yourself may not be considering applying to most of these schools (although you would be crazy not to since a lot of them especially northwestern are some of the best), you can see it would exclude a few important schools for most people especially since outside of california these are among the few that accept OOS in good numbers. LOL you can see why in my case I just had to get those 2 science LOR's (out of 25 schools...)
UVA
"The School of Medicine prefers a premedical advisor evaluation, or if this service is not available, a minimum of two letters, preferably from science professors or the equivalent."
UVM
"Two letters must be from professors in the sciences with whom you have taken classes."
Einstein
"Applicants who have attended a school at which there is no Pre-Professional Advisory Committee must have at least two letters of recommendation from faculty members at that school. One of these letters should be from a faculty member in the department of the applicant's major, and the other from a science faculty member.
If the major subject is science, the second letter should be from a member of a science department other than the person writing the first letter. Letters from Teaching Assistants will not satisfy this requirement, although TAs may co-sign letters with senior faculty."
Temple
If your school does not offer a committee letter or compilation service, our preference is to review an application with two science letters from faculty with whom you completed course work. If there is a compelling reason why you cannot obtain the two science letters, we will review your application with the letters provided. Please indicate in the supplemental application essay why you are unable to provide the requested letters. We welcome as many letters as you wish to provide for your application"
UCI
"Three to six letters are suggested. We recommend that at least two of the letters be from professors in the sciences with whom you have taken classes"
UCSD
"A minimum of three letters arerequired from individuals who can provide a well considered evaluationof your qualifications for the medical profession. (Two of the three should be from faculty with a science background at a four-yearundergraduate institution – course instructors, research mentors, clinical faculty are all acceptable."
Northwestern
"Your letters may be written by your college's pre-medical advisory committee, or they may come from three faculty members, at least two of whom are science faculty members, who have taught you."
UCSF
"We ask applicants who pass the preliminary review to submit 3-5 letters of recommendation, including at least two letters from your instructors...The letters that will tell us the most about you, your contributions, and your potential are those from instructors of upper division courses who know you well." - This one applies to most science majors
Jefferson
" If individual letters are sent, we prefer one biology, one chemistry and one physics and one humanities."
Case Western
"At least three, with two coming from science based faculty members. We recommend at least one letter come from a science class instructor."
Drexel
"If this isn't possible, students should ask three individuals who hold college-level academic appointments to send letters of recommendation. Two of these should be from science faculty and one from a faculty member in a non-science discipline."
