The temperature of an alcoholic frying batter (boiling away in the fryer) should be lower than a non-alcoholic batter, but with beer it's probably not going to make a meaningful difference. Batters made with hard liquor cook faster because they dry out faster though. The difference with your beer/NA beer might be due to sugar contents.
