as the only one who hasn't voted on an Oiler, I'd come up with such a theory too

I mean, there's a good chance the last Oiler is hiding amongst those six who did vote for Oilers. The question is why he/she would have done it. The Bonded voters had no reason to choose their buddy over agulati. The GGG voters had no reason to make it 2 Oiler lynches on 2 days.
