There are some tours still happening. But its now (supposed to be) only state/military approved delegations in some kind of official capacity: https://www.chernobyl-tour.com/english/161-visiting-chornoby...

It's possible some people still sneak in of course. But you're risking a non-zero chance of getting accidentally shot by a Ukrainian soldier mistaking you for a Russian infiltrator, let alone the legal consequences.

You're quite correct that Russia has been entirely pushed out. Heck, I would not be too surprised if Chernobyl tours reopen to the public after Ukraine occupies the part of Russia next to Chernobyl (maybe even Belarus if they do something stupid).
