I don't use `variable-at-point'. I do use a command that uses Emacs-Lisp symbol
syntax, which is the right syntax to use here.

Please stop trying to fix the command. The fix is to remove the useless colon.
Trivial.

That's fine, but it is totally unrelated to what I reported and requested.

(FWIW, the interactive spec of `info-lookup'
(`info-lookup-interactive-arguments') is very complex, requires specific
knowledge of the given mode, and so on.)

This is not about changing the command. It is simply about removing the useless
colon. Is that too hard?

Don't be ridiculous. You are making, in several separate ways, a mountain out of
a mole hill.
