Calling it Chidori or not is irrelevant. That's just a one word name that everyone will immediately recognize and know what we're talking about, not an argument in an of itself. Nobody's going to say "the lightning change in chakra around Sasuke's hand!" when they can just say Chidori.

When Susanoo actually appears says next to nothing about when Itachi started gathering chakra for Susanoo. These are mere details you keep arguing about, not facets of the argument that make a difference. Sasuke lowered his hand Itachi started reacting then and finished reacting when Susanoo appeared as the bolt hit.

It's no different than any of the other top tier ninjas would do. It pales in comparison to Sasuke summoning that snake, genjutsuing him, and jumping in his mouth to be desummoned in the ass pull of the century. And we know Itachi was faster than Sasuke.
