Yes, if you get caught in tsukiyomi and you are not uchiha you are a goner. Don't ask why. Go read the manga. It doesn't matter if you are hashirama, nagato and or kabuto. The genjutsu cannot be broken if you are not meeting those minimum requirements I'm about to list specifically from the manga:
1st: You must be an uchiha with an uchiha body and blood.
2nd: You must have MS awakened to break it. Don't use the sasuke vs Itachi argument. Itachi was just toying around with him.
At this point you must understand and take in the info I have provided.
BUT WAIT!!:
Here is the tricky part. Itachi is not automatically going to win a fight just because of tsukiyomi. Their are many who can defeat him by avoiding looking into his eyes.
For Example: Any reningan user has a high chance to win while avoiding eye contact. The shared vision can work as long as none of the paths look into his eyes. They can always simply look at Itachi from a distance to see what he is doing. No eye contact required.
Another Example: Hashirama would just kill Itachi with pure overwhelming power.
Another example: Madara would just smash Itachi, PF no other words needed.
Another Example: Orochimaru can fight Itachi, all he has to do is seal his vision.
I'm tired of listing examples but BOTTOM LINE IS:
Their are many who can fight Itachi and give him a run for his money without falling in tsukiyomi.
Now idk, but I'm sure Itachi would some how still manage to put some of the people I listed above in tsukiyomi. But what I'm saying, many can avoid it.
