I think it had more to do with Fisto and the other jedi being taken by surprise than anything else. They went to arrest Palpatine, thinking he would come peacefully like a nice old man. Instead they got a nasty shock from the darkside and before anyone could think of anything Sidious was upon them slashing with a lightsaber (which they also probably didnt think he had) and in the confusion Kitt just got cought by surprise.
