It depends more on player skill than on character skill.

For kiting them with arrows, lead them though the thickest parts of the forest. The obstacles will slow them down. If you do too good a job of that they might even wander off and you'll have to annoy them again. They can't step over fallen logs, they have to go around. They can't fit between trees that are too close together. Every shrub and sapling slows them down a little. Watch out for the greydwarf train you will acquire. Remember that greys and skeletons are natural enemies and you can make them fight each other.

Continuing with that point, if you dig a ditch with steep sides, the troll can't cross it. Usually I use this to surround my base. If a troll is following me, I lead it to base and shoot it in relative safety. (Still have to dodge the thrown rocks, and make sure you're not standing too close if it's a log troll.) If I don't have a base nearby, sometimes I ditch around a rectangular area, must be three or more across in the center to avoid logs, and use that as a troll trap. You can either sprint jump across the ditch or devise a mob-proof bridge. (A single balance beam, or leave a small gap you can hop across.)

Third way I kill trolls is with an upgraded atgeir. The starter bronze one is risky because it does very little raw damage to the troll, but it quickly gets better. A spin attack from any atgeir will stagger a troll. Follow up with a normal attack or two for damage. Watch out for the stamina drain.

Other people do well with parrying the troll's attacks. I never really got the hang of it, and practicing the technique seems very risky.
