I'd also like to note that Itachi was caught in genjutsu as an Edo Tensei by Kabuto. So just because you're Edo Tensei doesn't mean you're immune to genjutsu, and even one of Nagato's Pains were able to be caught in genjutsu by Jiraiya. So this goes to show that just because you're controlling something and flowing your chakra into it, it doesn't mean that it is immune to genjutsu. I don't know why the Edo Hokage were unaffected by Infinite Tsukuyomi, it may be because it is a unique case that only affects the living. But in the end, the only logical explanation for Itachi not bothering to use his genjutsu on Nagato is because he knew it wouldn't work on him and the only thing that can be attributed to is his Rinnegan.

Also, another issue with Itachi's side of this argument is that the Yata Mirror is the only thing that really even allows Itachi to come close to combating all of Nagato's abilities and possibly winning and nearly all of the arguments for this mirror are all based on overhype or very brief and vague explanations of it's abilities from the databook which in of itself seems to vary from translation to translation depending on the site and the databooks themselves have been incorrect and have proven to be flawed.

But on Nagato's side, nearly all of the things that have been argued for that would allow him to win has actually been proven and shown except for him being immune to visual genjutsu. However, there is still evidence to support that argument though as Itachi (Genjutsu Specialist) never bothered to use his primary fighting style on Nagato and the Rinnegan is the most powerful dojutsu (excluding the Rinne Sharingan of course) that has the ability to counter and dispel the Infinite Tsukuyomi. Arguing about the technicalities is kind of irrelevant, because Sasuke's susanoo being able to defend from the IT has been attributed to his Rinnegan, and it is the Rinnegan with the assistance of the chakra of all the tailed beasts that can dispel the IT. So really, there is evidence to support the argument that the Rinnegan is immune too or can counter extremely powerful visual genjutsu, while there is none suggesting that lesser visual genjutsu will work on it.

And even if the Yata Mirror really is invincible (which has yet to be proven) there is no evidence to say that it can absorb kinetic energy and can completely negate the momentum and force of incoming attacks let alone become an omnidirectional shield and completely change it's size and shape. It's because of all of this, that I'd say Nagato would definitely still win because he has so much more canon support than Itachi does. I mean, Pain/Nagato was called the strongest member of the Akatsuki with Itachi still being apart of it and Nagato was called the second strongest Edo Tensei (second only to Madara) by Kabuto himself. I'm not seeing how much evidence people need to support the argument that Nagato is more powerful than Itachi and will likely beat him the majority if not all of the time as long as they're on equal ground and a fair set distance from one another without any type of environmental or circumstantial advantages. The series has kind of made it clear who is more powerful.

Edit: So basically the only things that would allow Itachi to possibly stalemate or beat Nagato is visual genjutsu and the yata mirror, and there is no evidence to support the argument that the genjutsu will work on Nagato, and the yata mirror still remains a nigh-featless, unproven, and very vague item with next to no explanation of it's abilities (aside from an obscure databook, or Zetsu's statement which didn't really say much and was said halfway through the series and never brought up again.). So correct me if I'm wrong, but the logical deduction would be that Nagato would win when you put everything they each have canonically up against the other.
