Yes, when Itachi uses Tsukuyomi, he's actively altering their perceptions. So he's there with them torturing them. My theory doesn't run into any problems; by nature of the technique, Itachi's perceptions are sped up to match so he can actively hurt his opponent. You don't know that he doesn't manipulate his own brain; in fact, there's more evidence that he's in the Genjutsu torturing them than evidence to the contrary.

Why wouldn't being the castor change that?

If you read my response, I said "When he's seen Itachi use it before." Even if Itachi was the only user, the fact that Zetsu knew the technique at all shows that he's seen it before and can recognize it. BTW, all throughout that fight, Zetsu noticed Itachi was off. Every time Itachi didn't dodge or was sloppy, Zetsu noticed and said something. He never once questioned Itachi's usage of Tsukuyomi, but instead praised Sasuke for breaking it.

Kakashi looked Itachi in the eye and Itachi got Kakashi in an illusion. That illusion is passed through their eyes until Tsukuyomi is over, which happens in like a second. So Kakashi was looking at Itachi's Mangekyo with his own Sharingan the entire time. If that were an Uchiha, they could break the technique because the technique is being passed through their own eyes; their own Sharingan. And with the added processing speed that Itachi essentially gives the victim, they have a shot at breaking the Genjutsu.

Two issues with your last argument. Kakashi's statements aren't relevant to this discussion because he's refering to everyone there, who are non Uchihas. Meaning none of them can break Tsukuyomi on their own. The partner method would work on any other Genjutsu, but not this Tsukuyomi because they'd never reach their partner in time.

Here's the second issue; if Kakashi really was implying that if Chiyo could break out herself, it'd be useless, who is Kakashi to give that information out? He's experienced Tsukuyomi once, and he couldn't break out even with his Sharingan. What makes him the leading authority on Tsukuyomi, and what gives his word more weight than the actual user of the technique? Kakashi couldn't possibly know that it'd be useless even if you could break out on your own. Because as far as he knows, it's impossible even with the Sharingan. Unless you're an Uchiha, like Itachi said. The problem is, as far as it's known, putting the user (Itachi) in time dilation with the opponent, isn't a function of Tsukuyomi. There's no known method through which Itachi put himself under Time Dilation.

Zetsu does know about Tsukuyomi, but as far as recognizing it goes, he can only look at the external signs. He can't see what's actually going on inside. For all we know, Zetsu recognizes Tsukuyomi, by the opponent falling down, breathing heavily, before passing out.

Except Itachi himself, praised Kakashi for his analysis. Kakashi's words have weight due to Itachi and due to the fact he experienced it.
