I'd say you'll need to be at the swamp level in order to confidently melee them. So just mark the location, do some swamp stuff, and come back later to finish off those trolls. Be careful about starred versions, you may want to postpone those even further perhaps.

A sneak attack with a copper knife is usually enough to stagger a no-star troll, and you only need a couple more swings to kill it.

I personally wasn't aware during my playthrough and postponed killing trolls melee to a stage that was far from necessary in hindsight. Thanks for your input!
