Oh my lawd @Bob, I've told you before. "No holds barred" doesn't mean, "can use any jutsu no matter the consequence." Because for Itachi, attempting to use PS for more than a minute would put him either in a bed or in a coffin. You all saw how much Sasuke was hurting from using lesser forms of Susanoo, and this was when his eyes were relatively fresh compared to Itachi. And Sasuke has more powerful chakra than Itachi anyways.

"No holds barred" means that whatever they have the ability to do, they can do. Itachi does not have the ability to use Perfect Susanoo.
