Yes indeed if the two Olog-Hai are standing close together you might and I stress might be able to stun them both then get in close for 'some personal wet-work' and take them down. Best and shortest way I found was playing as Farin using his best crossbow and the Explosive Shot! One shot and you're toast Olog-Hai! Same demise goes for you Orc Captain with two Explosive Shots! "An angry dwarf is deadly Foe" a great dwarf line for either Farin or Gimli son of Glóin to use or say out when you're kicking the Enemy's butt!
