How to make a Lichess bot in Python
Clone https://github.com/lichess-bot-devs/lichess-bot.git into your new project! Make sure you have github installed!

Interested in creating, playing and testing your own chess engine?
https://github.com/ShailChoksi/lichess-bot is a straight forward way to use any UCI engine with lichess. There are also a few libraries for move generation mine: https://github.com/Disservin/chess-library , libchess: https://github.com/kz04px/libchess , surge: https://github.com/nkarve/surge . These are C++ ones, for rust theres https://github.com/analog-hors/cozy-chess . In python you could use python-chess but its incredibly slow for engine stuff writing your own will probably be faster if you know what you are doing.

I have created a chess engine in python. How do I modify it for UCI protocol?
I would recommend downloading this bot, written in Python: https://github.com/ShailChoksi/lichess-bot
Once you have these basic UCI commands implemented, you can use this application to run your engine as BOT on lichess.

I made a 1660 lichess bot
The bot uses the Shail Choksi's lichess-bot package (link) and stockfish. It's currently running on pythoneverywhere.com. I am very much a hobbyist and this is the first time I've done anything "useful" with coding. If you encounter any bugs, DM me and I'll do my best to fix them.
-
Is there a chess platform that explicitly allows computer play?
You can make a lichess bot with your engine (https://github.com/ShailChoksi/lichess-bot or similar API). The instructions are all fairly straightforward, but if you need any help feel free to reach out!
-
How do people go about testing chess engines against each other?
If you just want to make your engine play some games, with a uci interface you can quickly setup a bot account on lichess and challenge any available bot. https://github.com/ShailChoksi/lichess-bot

- TIL that chess is completely solved with 7 pieces(any combinations) left on the board. This solution is stored in a database table that's 17 terabytes in size.

Is this a draw?
If both sides play correctly, yes this is a draw. Chess is solved with fewer than 7 pieces on the board. At this website, you can check any such position and see what the result will be, assuming perfect play from both sides

Chess, unlike war, is a game of perfect information
There is some truth to this.
In theory, chess is a game of perfect information.
But in practice, this is only true for ~6-piece endgames: every outcome has been / can be computed. But for any middle- or early-game position, the amount of finite information greatly exceeds any person's or computer's capacity, practically speaking.
In concrete terms, the tablebase for 6-piece endgames is ~150 GiB. For 7-piece, it's 16 TiB.

Analysis board, practicing with the computer settings.
Alternatively, if you're playing an endgame with seven or fewer pieces, I suggest you use the Syzygy 7-piece tablebase to get the objectively best response on every move.

White to move and mate in 584 (longest forced mate ever found)
I suppose you mean the syzgy 7 man tablebases? Yes, they do take 50MR into account because they use DTZ metric (fastest way to checkmate, capture or pawn move).
-
What is the longest possible forced mate sequence with K - K + Q on the board? I managed to find a #10 at most but I suspect that you can get more. Has this been investigated?
I'd assume that Stockfish just hasn't found the M9. Tablebases already know the quickest mates in a given position, you can check the tablebase here
