What inconsistency? Kakashi blocked chakra lightning, which doesn't move anywhere near as fast as real lightning, as explained by Zetsu.
Because Kakashi explicitly stated that the chakra lightning turns into electric flow.

Lightning jutsu is the fastest element, and Kakashi confirms it's electricity created though chakra manipulation.
He specifies that Itachi can't dodge it becuase of of its sheer speed, not becuase he was exhausted. Nothing has ever been said about lightning jutsu that made it seem undodgeable, and iirc plant guy was watching Kakuzu's fight. Plus we can see how fast it is in the anime and its nowhere near as fast as regular lightning. And electricity doesn't = lightning.
