Lel, so, according to you, Preta can absorb sound waves? And no, Jiraiya already canonically shit on one of the Paths with Swamp of the Underworld. For your information, the MS eyes house the power
to control Bijuu. If Itachi's eyes can control Bijuu, I'm pretty damn sure he can control a few mediocre summons.
It took the Preta path a shitload of time just to absorb an Odama Rasengan.

Jiraiya, at 30 percent of his usual power, was able to make a swamp the size of this.
A full-powered Jiraiya is able to make a swamp 3x the normal size of this. Imagine the Swamp when it's enhanced with Sage Mode. The Preta wouldn't be able to absorb it all. It'd take forever. Jiraiya took advantage of the Preta taking a long time to absorb chakra. Since they're basically disabled when absorbing, Itachi uses a clone to explode the Preta to pieces.
Btw, Preta can't absorb Goemon. They're sound waves, not Ninjutsu. If the Preta could absorb sound waves they wouldn't of been stopped by the Toad Confrontation Chant.
Lol at you thinking Hebi Sasuke is stopping them with Kirin.
