And I will be using my GC in the GE machine, as I always do. But to get a BP, I had to say I was a visitor.

Then if I'm at the airport early enough, I will be sure to hand over the GC so they can scan it.

Really. A Canadian passport is sufficient documentation to enter the US. No visa, no ETSA.
AC is the one I fly at least monthly. They ask for my destination address (similar to when I told UA I was a visitor). That has also been my experience with NH in TYO. AC has never been shown my GC. I've had agents at other airlines ask if I have a green card inappropriately (i.e. Canadian citizen transiting the US certainly needs nothing other than a passport), but this only ever happens at outstations, and handing it over seems to make it easier for them, so I oblige.
But UA's system (since it's their home country) should be smart enough to know that if my passport entitles me to entry, further questions are irrelevant.
I can see how it could be more complicated for a citizen of another country, but as a Canadian, my passport is almost as good as a US passport when it comes to entering the country.
