Welcome to GB.
Well, I don't really use trainers so I can't really help with that.
Other than that, many of the enemies at the start of Divine Divinity range in ability, fortunately most of the toughest ones can be avoided and sometimes that is the best strategy. Save often and if you accidentally trigger a tough encounter reload and come back to it later on, when you're a bit tougher.
Do you mean the orcs underground or outside the town?
If you mean the ones found underground, then those are tough and an optional fight.
