Odin seems an obvious go to. God of wisdom and all that.
The celtic goddess of war, Morrighan, and her sisters Macha and Badb seem like they could make for pretty schway battlefield AIs, calculating strategies and brutal objectives(Morrighan was said to bring back jars of blood from the battlefield as gifts for friends, or decide the fate of warriors on the battlefield, Badb was said to be very shrewd and calculating, and Macha was spoken of as being the driving force behind the strength of will of armies)
Cernunnos, celtic god of the wilds, masculinity, and hunting would make a great AI warden for a game reserve or an AI-driven, male staffed brothel.
