Random encounters are keyed to your level, so you won't encounter many trolls in the wilderness or in caves until mid levels (10+ or so), but there is a cave on the coast SE of Leyawin that always has some trolls.
Also, an Ayleid ruin called Veyond, which is just NE of Leyawiin, is a troll hangout. When you get to the second level, the place is jumping with them. You'll probably be tired of trolls, before you get out of there.
