The closest thing to that that I know is this AFK Romhack AI v2.1 - seize, villages, and more
But it’s essentially just giving control of the blue units to the AI while making that AI slightly smarter than red/green units and adding things like visiting villages.
If you open a game in FEbuilder’s debugger by pressing F5, you can see a lot of RAM data that is documented there which you can make your program read during play.
