no they wouldn't have died Infinite Tsukoyomi is an eternal genjutsu so once a person is bound to it they are stuck in it until they are released by the caster or someone with a Rinnegan once there bodies are turned into Zetsu' they are likely still stuck in side a genjutsu for ever

the term genjutsu also doesn't necessarily mean illusion but Realty in general. Tsukoyomi for instance is technically a reality with in a reality its considered an illusion but it really is just a different stage of reality
