Which is an expected behavior of a gas, according to the kinetic molecular theory of gases?

Answer: The pressure exerted by a gas is independent of the shape of its container.

Really? If you put 100mol of a gas into a small, closed flask, only some of the gas molecules could be hitting the walls of the flask at any given time.

If you made some container that was 1 gas molecule thick at all points and of the same volume as that small flask, you could have all of the gas particles in 100mol of gas particles hitting the wall of that container, thus increasing the pressure.. right?

The pressure will be the same in both of them. It's really a matter of total energy of all the molecules based on simple mechanics mv^2/2 and having enough of them that statistically you can say that collisions are proportional to the area of the container. You will probably get lower pressure in a container so thin that molecules are too large to fit between two walls but what you have there is hardly something that can be considered open space.
