There was a Reddit write up that argued Tom was Arda’s spirit itself and had quite a few convincing points. It is pretty clear that (keeping in mind that canon is a bit nebulous beyond the four books JRR actually published) he is probably not a Maia and also probably not Eru, beyond the level that everything is Eru anyways.
My head canon was that Tom was Eru Iluvatar just living his best life enjoying all the things he’d created.
