Yes, it does use chakra, but not in the particular sense of actually emitting a force of energy into a nature or just your physical energy. We don't know how this is achieved, but considering how every other jutsu works, i'm fairly certain visual genjutsu is just some form of chakra transfer.

Not that it matters. Obito's genjutsu skills are sufficient that anything less than Tsukuyome won't even stop him, and i doubt Tsukuyome would hold him long enough to be a useful power. Considering the backlash MS powers have on Itachi and how easily Obito spams his, i think it's clear Obito wins this.
