What we did see was Itachi respect Gai' fighting ability, telling Kisame not to underestimate him. Gai also didn't show any fear standing infront of Itachi which is either due to extreme stupidity (Mutata' will go with this one) or a belief he could fight him. None of this means Gai could stand a chance vs Itachi though.
I for one think Gai couldn't defeat Itachi. Gai never shows any sign of him believing he could win, just that he could fight him till reinforcements could appear.
