You can set up a fictional league so that when you add fictional players, it only creates them in the states you’ve gone in and manually assigned. I *believe* there is now also an option to have a “regional draft” after your regular one (well, in theory; I believe that exact feature is bugged right now and we’re waiting for a fix) and you may be able to draft players by state “regions”, but short of preventing the AI from signing players, period (which is certainly an option) I don’t believe you can tell it to only sign guys from an individual state.

An alternative way to set this up is to modify the world.xml file to make each state into its very own “nation”. At that point you could then assign each team a nation “state” and set “foreign players” to 0. If you want to use historical players you’d still need to manually assign them to each nation “state” (or edit the players file programmatically, which is probably what I’d do, but I write code for a living and some people find that a larger hurdle than hand editing every single line of a file) but I am 100% positive that works for real nations and fictional players.
