Again, Itachi was just about blind, it was raining out and it was dark out. All he saw from Sasuke was a dark blur in the distance, Itachi was listening to Sasuke's voice and heard where he was coming from. From there he reacts to the change in light when Sasuke has Kirin summoned. Itachi himself had to have PERFECT reaction speed and timing so that Kirin didn't kill his blind and near death self before he could rid Sasuke of Orochimaru. So that indeed is a feat for Itachi and it is an insane feat considering he was just about blind and near death. You also forget that Zetsu even mentions Itachi's movements and performance are slower and worse than what he has done before showing that Itachi was on his literal worst day of his life physically and all and still managed to do all the things he did and still reacted to and blocked Kirin with Susanoo near perfectly. Kakashi had NO excuses and he also had the Sharingan at the time, he wasn't blind and he was't near death. He saw the lightning clouds and went to where the lightning was predicted to fall by him and lifted his hand and caught the bolt coming down(the anime's portrayal is he didn't really cut it). He was using Chidori which is lightning release.. which attracts lightning and can counter lightning as shown vs Kakuzu, Itachi had no lightning release just to add on further to his feat.
