Yes he can. Not that he would ever be caught by fodder level genjutsu.
After explaining aw d justu worked to gaara nd onoki it still took dem time to break out of dat genjustu

Itachi would work out the genjutsu's mechanics quickly and locate the Giant Clam with his Sharingan. Following that, he could use a small burst of Amaterasu on Joki Boi and take the weakened Trollkage out with some well-aimed kunai.
They knew it was d giant clam they had to attack bcuz the trollkage told them how would itachi know
Itachi could find and destroy the clam...
i have no idea how he would stop the Joki Boy, maybe Totsuka Blade...
