One of the samples claimed to be an agent acting on the behalf of a client. Google says they're still deciding on the best format for these calls--here's hoping they take the criticism of people like you into account, and go with something like that example.

Of course, I don't really see why there needs to be an attempt to pass as human at all. It would be fine with me if they just reinvented the phone tree with a better ux. Especially since it's billed as a business-facing call.
