Don't think there's explicitly a God for Chaos machines. It's kind of ambiguous whether the Dark mechanicus still worship the Omnissiah; they certainly don't in the same way that the loyalists do. It's all pure rationality for them, they actually use scientific understanding and innovate new technologies, although they have Warp screwery to assist them.
