Pretty sure shes good and wants to help the UBs, it seems in the post game she takes over the Aether Foundation and the character and Looker go out and catch all the UBs.
https://projectpokemon.org/research/sunmoon/storytext.txtIn one of Lillies Diaries -
I have to leave Paradise so that I can protect Nebby. I told Wicke about my plans in secret, and she told me I should find someone named Professor Burnet and speak to her, that she might be able to help...†“Wicke thinks that this Professor Burnet woman is researching the Ultra Wormholes. I wonder what kind of person she might be? And how will I ever find her? I don’t even know where in Alola she might be right now...â€
"Our truly final mission requires that we go to Aether Paradise and report to Ms. Wicke that we have contained all of the UBs."
I dunno I think Wicke is the only genuine one and the rest of the leaders are corrupt.
Theres text about Lillie seemingly seeing her as a better mother figure than Lusamine
