It does pose a lot of questions. I think the only statement about Lilith being biblical Lilith is made by characters reading lore. The purgatory=Eden thing would tie lots in to a bow. Like the pagan gods, very obviously some brand of monster in the SPN universe. Also leviathan is a sea serpent with a lot of similarities to the ancient mesopotamian tiamat, who was like the primordial chaos the universe came from.

So for it to be bible eve the lore would have to be different on a lot of characters... so i dunno
