<p>^^My guess is that a non-religious Jew would feel pretty comfortable at Georgetown too. (I can’t speak one way or the other vis-a-vis BC or Villanova.)
As for Brandeis, a generation ago it was something like 85% Jewish. As a non-religious Jew myself, that was just way too high for me. I was looking for a more diverse place, preferably in New England, where I could be part of a sizeable minority. I went elsewhere.
I visited Brandeis in recent years with my kids, and have lots of friends whose kids are recent grads. Brandeis’s Jewish undergrad population now tends to be closer to 50%, and that covers a wide range of levels of observance, so a culturally Jewish, but non-observant kid would feel perfectly comfortable there now.
Good luck to your daughter wherever she goes.</p>
