I'm not sure about Case but I went to OSU and each department had a link to research labs open to students (ex. if I went to the psychology department website which was like psychology.osu.edu or something like that, one of the tabs was about research). There will usually be someone's contact info who works in the lab, it's most likely a graduate student or a lab manager so you probably won't be talking to the PI directly at first.
I mean, the worst thing they can do is say no. If you end up in a class with one of these professors you can reach out again after you know them a bit and just reference how you've been interested in their work and would like an opportunity to do research under them. I do believe that while Ohio is in Phase II, at least at OSU, they're not having everyone come back - most of my friends who work in academia there are still working from home. So if there's a specific task you think you can help with (documentation, data entry) that you can do at home that's suitable for the project you can mention that, and it'll help them see what you can offer at the time. I think given the current situation, getting into a wet lab to do hands on tasks might not be feasible.
If you aren't able to research but you're able to get out - go volunteer! A lot of places like the blood bank, food bank, homeless shelters, animal shelters, ect. had an influx of volunteers at the beginning of Covid but now desperately need more people. Places with generally older volunteers like polling locations and soup kitchens, now have mass shortages. Volunteering and showing you have a commitment to helping people less fortunate than you is just as important as research.
