To be fair to Google, though, this is a cultural problem. The mute and camera buttons depict the current state in basically all telephony applications (see Skype, Zoom, Discord ...) and the red "hang up" button is also the expected form. Yes, it's a bit inconsistent, but I can see why they make the buttons inconsistent within themselves rather than breaking user expectations. This does not excuse the placement, though.
