While Gai probably wouldn't win, I'd imagine that Gai would put up a better fight versus Itachi because Gai excels so much more at Taijutsu compared to Kakashi, and as stated, the worst match-up for the Sharingan is Taijutsu.

As for how fast Itachi is, we've seen that sort of speed from Gai as well, the kind where you don't even see him move out of the way.

Again, Gai likely would not win, but do not discount him. He may be on Kakashi's level, but he's still better equipped to fight Itachi.
soudns reasonable but gai's speed and itachi's speed are diffrent itachi got jutsu speed, he does jutsus as fast as gai moves which would make it very very hard for gai to fight since itachi can follow ga iwith the sharingan.
