In fairness , it seems Leela zero could have won that game by NOT shuffling on move 78. The pawn break e4!was decisive , and Leela missed it. Stockfish own PV lead to an ending with Rook and Bishop for Leela , Rook and Knight for Stockfish, with Leela a pawn up. I analyzed with Houdini 6.02 with TWO iterations of twenty minutes each , going in the first so ...
Can the player with Black claim that White is being unsporting by
shuffling and refusing to accept a draw?
No. White may be quite legitimately trying to win on time. In blitz this is always allowed. In longer formats it depends on the format.
Are arbiters permitted to adjudicate if one player isn't making an
active attempt to win the game, but seems to be ...
I suppose what is comes down to is that the way 3.8.2 is written can be argued to have a syntactic ambiguity. 3.8.2 can mean either "This is a move of the king, and either rook of the same colour, along the player’s first rank," or "This is a move of the king and either rook of the same colour along the player’s first rank."
There's no ...
Clock runs out and they lose on time if it is the move of the dead player.
Otherwise the opponent could resign or move; unless a draw was offered before the death in which case they could accept the draw (why?) , resign (but more why?), or move and wait for the clock to run out on the now dead opponent.
Is there any glaring flaw in this rules lawyer case, or is it solid
until FIDE fixes it?
Yes, there is a glaring flaw in your case. The rook and king have to be on the same rank. This is clear from the text of the rule and the diagrams which follow. Here is the text from the latest FIDE Laws of Chess:
3.8.2 by ‘castling’. This is a move of the king and ...
The history of some chess positions can be determined with certainty and some cannot.
PRA looks at each alternative history and finds their different solutions. These typically revolve around if the right to castle exist, then you have some solution; or if last move allows en-passant then another solution exists.
RS involves 'mutual dependency', for ...
Just to clarify IA Petr Harasimovic's comment in the answer provided by Cleveland, here is a position in which capturing en passant is illegal due a diagonal pin.

On the first and third pages of the post that seemed to make the world go crazy on the subject, there are a few given historical problems that feature the "legal" triple check along with historical details. It even made a recent appearance in Episode 20 of "The Chess Pit" at the 12:13 minute mark.
The dubious wording of the law in ...
The international chess federation has published the FIDE Laws of Chess which give the rules for playing chess.
"Article 2: The initial position of the pieces on the chessboard" would be a good place to start, followed by "Article 3: The moves of the pieces"
Resigning immediately after a checkmate is not possible. HOWEVER, the FIDE rules do allow for a player to do another action, namely withdraw. Withdrawal can be done outside a match and for the most part has the same result, namely that the player is no longer part of the tournament. However, there are penalties involved with this action if the FIDE arbiter ...
