At this point Lolorito is neither an antagonist nor a good guy, if his intent was to gain power he already had the chance and decided not to take it, his only intent is money and by being in our good side he's making a lot of it, we even indirectly help him through two side quests, one where you help his... niece? in Kugane, and another where you facilitate illegal trade between his company and the confederation, on top of him likely trying to be the first to make trade deals with the two cities you liberated. As long as he's gaining something from it he's not gonna work against us.
