I'd like to create a little mode-line "lighter" that will show which
combination of modifier keys is pressed. (My keyboard has a sticky
key problem, so this would help me diagnose how to unjam the keys.)
Does Emacs know which modifiers are "on" at a given moment?

No. Certainly not at the lisp level. On some platforms that do not support all modifiers being applied to any key, the C code has knowledge for some modifiers, but it isn't exposed outside of the keyboard handling code (see mod_key_state in w32inevt.c for example)

Emacs could know (at least under X11 and probably under other GUIs as
well), but it currently opts to stay in the dark.
