@Ninja of War:

The last part, the part where Sasuke brings his hand down, is the only part that matters. Unless Itachi can predict exactly when Sasuke is going to bring down Kirin it doesn't matter. Since in your scenario he can't react to Kirin, it doesn't matter if he knows it coming, if he doesn't know exactly when it's coming. It's like I said the margin for error is extremely small, too small for that to be realistic.

@AsianReaper:

Susanoo is a giant mech made out of chakra, how could he miss it, unless Itachi brought it up like last second?

1. Because it's a possibility, which means he couldn't have been sure of exactly when Sasuke was going to bring down Kirin. Also, because after Sasuke said "begone with the Thunderclap" it took some time (probably a few seconds) to bring down his hand, that means that, as far Itachi knew Kirin could came anytime within that time, since he wasn't watching Sasuke and know when he brought his hand down.

2. Kakashi could of just stood there with his hand up. There's nothing that suggest Kakashi mentally, let alone physically react to lightning.
