The fact that Kithraak leaves the task to his soldiers, shows how githyankis, especially him, underestimate the creatues of Faerun, specifically the player's party.
I think this fits rather well with their arrogance and thought of superior combat skills, a decision that he is going to regret later when he finds out that the player's party made short work of his kin.
Good point, actually! Maybe for clarification, he could say it out loud (or Lae'sel could) but it does make sense.
