Some animals certainly do. They’re not necessarily bound by our morality by any stretch of the imagination, but absolute some animals likely have free will.
As for reflex versus choice, if someone hits my knee just right my legs going to kick out. If someone pushes in the same spot and says “kick your leg out” and I don’t want to, I don’t have to.
There may be constraints on that, obviously at gun point I’m going to, but yah, if you’re able to think about then choose to do something or not do something that seems qualitatively different than a reflex.
