Conjuring up an nearly instantaneous defense to an extremely telegraphed attack is not that impressive This was done in genjutsu, but is still something I feel is worth considering, why would Itachi not use his normal moveset in that illusion? not using his normal moveset would immediately relay onto his opponent that it's a genjustu, hence making it pointless to use a genjutsu in the first place. Oooor Itachi wanted to deal mental anguish considering that, in the genjutsu, he plucked out Sasuke's eye. So, the speed displayed in the genjutsu should not be taken seriously
 * Even if Kirin was telegraphed, Itachi still had to do the reacting. A baseball player would know that a pitcher would be throwing a ball at him, but it's still up to the batsman to react and hit the ball.
