So, this is why the Tolkien Estate and creators in general are pretty much obligated to state that fanworks are not officially authorized: so that if a fanwriter does try to claim the IP belongs to them, the IP's actual copyright-holder is empowered to take legal action. They probably would still choose not to in this case, since it doesn't sound like there's much chance of this person actually convincing anyone they own whatever canon and profiting from it, but if that ever became the case, that person would rightly earn a Cease & Desist.
You're right not to draw attention to them. It sounds like they're living in a delusion, not actually trying to steal and profit from an IP. Best to leave them alone.
