Best to say it's in the misc. category, as it is a cultural god. In terms of using "aedra" and "daedra" in the sense of "Ancestor" and "not ancestor", I'd call it "aedra."
But whether it gave itself up to make up the world, I have no idea. And if we're going with that definition of aedra, Talos wouldn't be an aedra either, and thus a misc.
