Black zetsu aka kaguya's will admitted that itachi was invincible with yata mirror and totsuka blade. Black zetsu has seen madara and hashirama power yet never called them invincible, and he has lived for 1000 years. Itachi can obviously beat kaguya as she isnt an experienced ninja nor is she intelligent as she fell for naruto's sexy jutsu and was outsmarted several other times in that fight. The yata mirror blocks all of kaguya's techniques and since regular swords can pierce the ridoku cloak, the totsuka blade can easily pierce and seal her away. You guys have to be seriously not reading the manga or databook to be so oblivious to the yata mirror's abilities.
