Couldn't you just install the Google Profile on any android tablet or spare phone or something, set it up, switch to authenticator (on your normal phone) and then remove the accounts and whatnot from the tablet? Never use SMS at all?

The real head scratcher for me here though is that you are fine with Google hosting all of your emails and whatnot but knowing the phone number is a huge problem? If you do not trust Google with your phone number it seems like going with another email service would probably already be a good decision.....
