Hard to recommend anything specific since we don’t know how you’re doing things atm. Perhaps you could take advantage of Pawn Sensing, If the AI detects Player Pawn, they run away in the opposite direction:
You get to control some params here.
If no Pawn is detected, the AI can return to whatever other routine you set up.
You could use a sphere overlap on the player pawn to send the AI away in a very similar way instead of the Pawn Sensing comp.
