How the Lc0 Training Games Work (In Windows)
So according to the Releases page at https://github.com/LeelaChessZero/lc0/releases on the 1st of January 2022, Lc0 was in version 0.28.2. That takes care of the [White ""] and [Black ""] headers. To get the ratings, I went to the CCRL and looked it up: https://ccrl.chessdom.com/ccrl/404/cgi/compare_engines.cgi?family=Leela%20Chess

Setting up Maia chess locally and making it play unique games
Sorry, I should've said it in a more clear way. The feature isn't broken in general, but it wasn't intended to be used for randomizing move selection by policy value (normally it uses number of visits, if I understand correctly). This was changed in this PR so I don't think there's any issue that needs to be reported.

FM Dennis Monokroussos' Open Letter to Ken Regan + Regan's response
UCI is designed to interface with GUIs. He needs it to be usable in "batch mode" which means providing input games/files on a command-line. I just looked at the lc0 documentation. There doesn't seem to be any way of integrating a batch mode https://github.com/LeelaChessZero/lc0/blob/master/FLAGS.md

Can you find the only winning move for White?
If you are curious where this game is from, this is actually a computer chess game that I ran on my machine between Leela Chess Zero 0.29.0 prerelease on https://github.com/LeelaChessZero/lc0/releases (CUDNN) playing with the black pieces, and Stockfish 22060708 64X BMI2 on https://abrok.eu/stockfish playing with the white pieces. The game continued 17. Bxe6 Kxe6 18. f4 Nxf4 19. Qg4+ Kd5 20. Rxf4 gxf4. If you check that position with Stockfish 15 NNUE on chess.com, it should realize that it is winning.

What's a simple engine to modify? (Preferably in Python)
I suspect in a PUCTS based engine, simply changing the parameters to make the search wider could have the effect you want. Ie, the engine will try losing moves more often, which reduces the expected value of a node if it doesn't have a lot of similar options. I haven't checked Leela out in a while, but there is a good chance you don't even need to modify code to try that. https://github.com/LeelaChessZero/lc0
