Is there a premed program at university of Illinois at urbana champaign? And is there a good med school in Illinois?

It's actually a common misconception that pre-med is a major or program. "Pre-med" simply means that you're planning to apply to medical school, and that you'll be fulfilling the prerequisite courses to be able to apply. You can be in any program or major and still be "pre-med" (you could major in Spanish or Music and still be pre-med, for instance). Most pre-meds simply end up being science majors because the prereqs are mostly science courses.

What this means is that there isn't a pre-med program at the University of Illinois Urbana-Champaign, nor any other college. But, you can be a pre-med and attend UIUC, or virtually any other college. What you'll want to look out for when picking colleges as a pre-med are: depth of science classes, strength of pre-med advising (many schools have pre-med advisors who make sure you're on track with courses, and help you with your med school apps), availability of research opportunities, and a few other major factors, mentioned in this CollegeVine video: https://www.youtube.com/watch?v=MzMyf-6ErQY

It looks like there is pre-health professions advising at UIUC, and there's a whole webpage with other pre-health professions resources: https://www.careercenter.illinois.edu/instructable/pre-health-illinois

As for the second part of your question, there are several good med schools in Illinois - UIUC does have a medical school ranked 50 in research and 48 in primary care. Other highly-ranked schools are UChicago and Northwestern. Med school admissions in the US is extremely competitive though, and it may be difficult to limit yourself to a single state.
