I figure it's the latter, which would make booking with an AA partner a bit of a risk. I don't think those partners can force award space open, either, if there isn't any.

You would need to work with the airline that issued the award ticket. That airline can open additional award space on its own flights, but can only request, not force, its partners to do so. If you are not satisfied with the alternatives offered after a significant schedule change, you can receive a refund of your miles and fees and then start over.
