Minnesota does offer need-based and merit aid to international students. The average award amount is only about $3300, which would only cover about 10% of the costs. Maybe your stats would merit a larger award. It’s hard to say, but keep in mind that about ~5500 freshmen enter UM each year. The number of available merit awards appears to be smaller than the number of students with stats as high as yours (or higher). Presumably, Americans (esp. Minnesota residents) would get first crack at them (unless some sum is held off for internationals).
Macalester College is a LAC in the same city. It, too, offers both need-based and merit aid to international students. However, its average award is about $42,000. In 2014-15, Mac granted financial aid to 215 international students (compared to 180 students at Minnesota, a school with about 10X as many freshmen as Macalester).
Here’s a ranking of colleges in Minnesota:

Macalester is #2, Minnesota is #8.
I’d say that among people very familiar with the US college system, it’s a more prestigious school than Minnesota
(although these things are somewhat in the eyes of the beholder).
