"Default layer state" of what, exactly, and for what reason?
There is no Action to change the layer state. A custom Action could feasibly written - but depending on why you want to, there may be an alternative solution.
There is an NPC who is going to be crouching down looking for something then when we give her the item she is looking for she's gonna go back to her seat in the train and go to the idle animation but I guess I could make the idle loop?
I'm afraid I'm still not clear on what it is you're asking - please see the forum rules about the detail needed.
If you're looking to change the "idle" animation, however, that can be done with the Character: Animate Action. Screenshots of your set-up, plus details of your NPCs chosen Animation engine, will be needed to help further.
