Um no, there is nothing 'supernatural' about Susanoo. It's well documented as being a construct of Chakra and has been shown to have plenty of weak points in Databooks, Manga and Anime regardless of the nature of the Blade and Mirror. Plus Itachi's Mirror doesn't provide him 360 degree protection, Itachi is not undefeatable by any measure.
