- 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

Rare "bipartisan" win: Lichess tweets about a Chess.com stream and Chess.com acknowledges
Pychess seems to be maintained by a completely separate entity. The name is also incredibly badly chosen, because PyChess is a well-known, unrelated interface GUI written in Python + GTK.

Chess GUI for Ubuntu
I am Using Ubuntu 20.04 and want a chess GUI, tried Pychess, but it sadly doesn't work with editing time control, so I created a issue https://github.com/pychess/pychess/issues/1910. Can someone please help me to find an alternative chess GUI instead of pychess for me?
What are some alternatives?
When comparing syzygy-tables.info and pychess you can also consider the following projects:
python-chess - A chess library for Python, with move generation and validation, PGN parsing and writing, Polyglot opening book reading, Gaviota tablebase probing, Syzygy tablebase probing, and UCI/XBoard engine communication
