Are there known jobs for Trolls?

Lower bloods are known to become butlers, and likely also waiters and jobs related to service in that sense. Vendors of various kinds are also valid jobs, as we see with Ticket Vendor on the Concept Art. Skylla implies farm work is a thing on Alternia, Apiculture and Game Development may also be potential jobs. Goldbloods eventually may become Batteries for a Ship so you could count that as a job. Jades are bound to caretaking in the Brooding Caverns. Law jobs exist, as do various sort of like, military rungs for the different castes. Likely also jobs as the crew of a ship. Janitorial jobs… There’s a bunch.
