allAuthenticatedUsers does act a documented, and applies to all Google accounts. Since you're using an organization, you can use the organization's domain (e.g. example.com) to grant roles to all users of the organization. This is noted in our FAQ: https://cloud.google.com/iam/docs/support#to_what_identities_can_i_grant_cloud_iam_roles
We could make this more clear elsewhere in the documentation, so I'll see that we update the docs around this.
