You can make KataGo play moves that keep the score roughly even since it has a trained score head, e.g. kataJigo [1]. This will keep the game even to your level, a nice way to train.
For training you really want your good moves to be rewarded and your bad moves pointed out, but if the AI just plays up or down to match what you do instead, there's no signal getting back to you on how you're doing.
