There is no reason why Sasuke couldn't use tsukuyomi
I've seen many people saying that Sasuke doesn't have tsukuyomi, but i believe it's a wrong way of thinking. Sasuke does have tsukuyomi. It's only that his mastery over the jutsu is not as good as Itachi's. The simple fact that Danzo compare their tsukuyomi proves Sasuke has it, albeit not at the same level as Itachi's. Even Obito purposely differentiated Itachi's tsukuyomi to Sasuke's, which further implies that Sasuke has it.
So contrary to the popular belief, Sasuke's MS genjutsu is tsukuyomi. But the only difference between Sasuke's tsukuyomi and Itachi's is that he is unable to control the length of his illusion.
Some people believe that all tsukuyomi last 1second or something. But that is wrong. If it was the case, then why casting infinite tsukuyomi? It's only that Itachi is able to control the length of his tsukuyomi to such an extent that it can be casted in just an instant if he wanted. But it doesn't mean that tsukuyomi originally only cast an instant. Itachi himself intended to use tsukuyomi for a very long time since he needed to take control of Kabuto for minutes in order to comprehend how Edo tensei work and actually control kabuto with it to stop it.
So like you can see, the duration of tsukuyomi depends on the user and also his chakra reserves. More the tsukuyomi takes long, more it takes chakra to maintain it. So since a one second tsukuyomi already took a tole on Itachi, i'm not sure if he can maintain it for that long if he is alive for example
For those who still don't believe Sasuke has tsukuyomi, manga showed that there is no reason he doesn't have it. Manga has shown that all what you need to use Ms techniques is having the eye power. Itachi, Danzo or even a simple crow are able to cast Shisui's Kotoamatsukami just by having his eyes. Sasuke himself has Itachi's eyes currently. So there is no reason why he could not use tsukuyomi. If he really couldn't use tsukuyomi, then it would be shame on Sasuke's side since it would mean that a crow is more talented than him
Normally he should have Itachi's Susanoo items as well, but since it's probable that those items are not Itachi's eye powers but instead items Itachi found somewhere, it can be a possible explanation why he doesn't have them
