Given that we are hearing announcers talk about exit velo, it’s a safe assumption that we now have Statcast for college baseball.
Rapsodo & Trackman is where they're getting the numbers from. We've had them for quite a few years, it's nothing new. Sharp & McLaughlin have periodically mentioned exit velos and spin rates ever since Erstad was Head Coach. I do agree it seems like they're mentioning it more this season but that's baseball broadcasts as a whole.
Synergy is what college programs have been using the last few years as far as scouting reports, obviously all teams have access to other teams data. I don't believe it's readily available for the public though. It's incredible what it spits out, but it's not like Rapsodo, Trackman, Statcast or Savant...
Synergy will give you data on, as an example; what pitch is thrown in every single count of each pitcher, against LHH or RHH, number of outs, bases empty, runners on which base, which inning, pitch count category, so on & so on. Same thing the other way around for hitters, it breaks it down under every situation a hitter has faced.
