I don't think Lolorito is working with Dravanians or even Ascians, at least not directly. Lolorito once stated that his company did trade with the Garlean Empire before it became obvious they wouldn't settle for anything less than complete conquest of Eorzea but, given his personality, I don't believe him. He's a pragmatic backstabber, he wouldn't break off trade so easily - especially when he can just do it underground rather than overtly - and he wouldn't be so loyal to the other city-states that putting Ul'dah on the side of Garlemald would be beyond his scope. So long as he can arrange things to keep himself above others in terms of power and wealth, I wouldn't even put him above attempting to sell all of Ul'dah to them, subjugating the city-state through use of his followers in the Crystal Braves and Brass Blades.
