AI is observably worse for one side in 100% AI matches

The AI in definitive edition is pretty good overall, but I can't help but notice a very strange anomaly. When running all AI games which is something I like to do while puttering around with other stuff.

I run 4 vs 4 matches mostly in Arabia or Black Forest and team 1 will lose about 90% of the time. Over time I've observed the games and noticed two things that regularly cause team 1 to lose. For some reason the pockets are often slower to send military and will let a flank be double teamed and wiped out.

The 2nd thing I notice is that player 1 has a suicide protocol of sorts. Every single game it will completely throw the game by endlessly sending villagers to build things like mining camps and town centres in the middle of the enemy base.

I'm wondering if there's a better AI mod for the game or something like that. It takes the fun out of my idle experiments when I know one side will actively throw the match.
