I think the only place we speculate is in the Fall of Guardia theory page, where perhaps Lucca agreed with some kind of theorized anti-monarchy movement. Seems unlikely though in light of CT DS, as she'd be selling out her friends to help Dalton's new empire.
Since she's probably decent at robotics, perhaps it was components for Grobyc, etc. used to finance the orphanage post-Fall of Guardia.
