I'd say that depends on the distance, but in general, sure, why not
 * Itachi can oneshot any slow/slower or really large opponents - for example tsunade, sakura and the bijju's with just amaterasu or SOT (same with sasuke ofc for amaterasu)

I'm not sure on this, Jiraiya said that to break out of a genjutsu you need chakra potency or something like that, so I belive that jinchuriki, people who have aquired SM, or general people with a stronger chakra are either immune or can break out of it
 * Any non dojutsu, or weak dojutsu users can be one be shotted at first glance with tsukuyomi via statement and feat.

If you give it to his as a battle option sure
 * With a readily reprogrammable kototamstksmai crow he was easily the strongest person in his time, as he could have easily one shotted the strongest either with the above or this.

I tend to not consider this tho, same with Danzo

Itachi also had the crow to use only in case Sasuke had gone bad, to be sure he wouldn't fail Shisui promise given that he leaved his brother alive, so in "in caracter" fights it shouldn't be considered, but in "all out fights" sure (Idk if it's easly reprogrammable tho)
