It has to have been written, because it rhymes with "nowhere that we'd rather be" and additionally the harmony in that line (if there is a harmony, they might be singing unison and it's hard to tell) includes a flat note. https://en.wikipedia.org/wiki/Flat_(music)

To go into more detail, the chords for "and there's nowhere that we'd rather be" (nine notes/syllables) are (in the key of E♭ major) A♭ major (IV "four" chord), G♭ major (III♭ "three flat" chord), and then E♭ (I "one" chord). The melody, which I'm assuming is Starlight here, is "G-B♭-C-C-B♭-B♭-B♭-C-B♭", while the harmony, which I'm assuming is Trixie though I can't hear it that well from her voice, is "E♭-G-A♭-A♭-A♭-G♭-G♭-G♭-Eb". (I bolded the flat note that would make Trixie question how on-key she is.)

Or heck, just look at this example I whipped up in Musescore: https://i.imgur.com/85Le94O.png

So that's why I think Trixie asks/Josh Haber wrote "Was that off key?"
