You can play with thrall attack/chase distance though? My thralls never run away even when the camp is literally behind the walls of my base and have no issue returning to their guard location. If anything I’d like my defending thralls to be more aggressive than they currently are, sometimes enemies reach the coffer before my melee thralls had time to react, and a demolisher might get one hit or two in before my berzerker on guard station wakes up.

But I don’t mind doing most of the work since the AI is so dumb anyway.
