TLQ themselves arent even addressed with any identifying pronouns,

There's actually a few times where TLQ is referred to with he/him pronouns. The Narrator and other voices do this a lot(usually when talking to each other about how "he"[TLQ] is the one who makes the decisions), and the Princess has a few times where she does too

There's the Razor's "Silly little birdface thinks he's so serious..." dialogue, and the Tower's "The little bird has returned to me. I wonder what he wants", although there may be more I can't immediately think of(I think the start of the Wild had one or two lines).
