It cant be Kirin and heres why.
For one, when sasuke put his hand up in the air he looked as if he was about to slam his hand down on the floor as if he was going to do some kind of summoning jutsu
2.) Sasuke would have made hand seals for the grand dragon jutsu and would have been aiming up into the sky so he could prepare the thunderclouds if "that jutsu" was in fact Kirin. The day was bright and sunny so you guys cant say "there was no need to it was already raining and had thunderclouds" cause unless im blind it was it had more sun out than florida in the summer.
3. Orochimaru stopped his hand just as he was going to use his "that jutsu", and said "hey there no need to use "that jutsu" here" showing that sasuke was indeed about to let off his that jutsu.
So with out taking the preparations needed as seen to perform Kirin we can safely say Kirin wasnt "that jutsu". oR WHAT WOuld have been the point for sasuke to create all those thunderclouds and waste all that valuable time if he could have just used it as is ?!?!? think about it, be smart. Dont let hate cloud your vision.
