I can't speak for Google Brain specifically, or AI/ML (I do InfoSec). Perhaps there is a need for discussing the Google Brain project specifically from a woman's point of view.

But when I hear about a 'Google Brain Women and Allies' distro, I'm more thinking about peers which discuss things which impact them. I wouldn't get too hung up about the 'Google Brain' portion of the distro; it's likely just a way to self-select a group of peers which share a common interest.
