Ohio State Marion does award merit to visa holders that qualify for in state tuition. Marion has a different pool of money to pull their scholarships from and has some good funding for students.
I noticed their merit aid does not have the qualifier of US Citizen or permanent resident that the merit awards on the main campus page (like Maximus, Morrill, etc) do, so I reached out to Marion directly to ask and this is an excerpt from their email:
We do grant merit scholarships to students with VISAs that qualify them for in state tuition and graduate from an Ohio high school as long as they meet deadlines and the criteria. However, you may not get any federal aid such as FAFSA. Please let us know if you have any additional questions!

OP, I want to point out that this would be an excellent safety for you. I think it will come in budget for you. The pre-med classes are very standardized with the departments running the exams for introductory classes. There is no difference on your transcript if you take Chemistry at Marion or Columbus. The difference is that at Marion you won’t be in a huge lecture hall and your recitations are very likely to be led by your professor. My S had classmates that drove up from Columbus specifically to take some of the Marion classes on the smaller campus just for that reason. Marion offers an honors program and research opportunities as well. As long as the majority of your classes in the semester are taken at Marion you can still get regional campus pricing.
One of his engineering classmates commuted from Cincinnati twice a week for a semester. The student had been accepted to a great university but his outside aid did not stack as expected and he had to find an alternative at the last minute. Just like there are students at flagships because of financial reasons, there are some at regional campuses, too.
If you are able to increase your budget in a few years you can complete your degree at main campus. If your budget remains tight there are degrees you can complete in Marion. The Marion campus also has good ties to OhioHealth, a large non-profit healthcare network in central Ohio.
Please apply directly to the Marion campus so that you will qualify for their merit and meet their financial aid deadlines.
Unless your parents are willing to pay the full in state cost of Ohio State main campus in Columbus, I don’t see the point in applying until you have a green card. All of the merit I have looked at there requires US citizenship or permanent residency.
