If you are going to bring up a sport as an analogy. Football is a terrible choice. Baseball is much better, Youth baseball has a mercy rule to prevent complete humiliation of one team
"It is especially common in baseball and softball in which there is no game clock and a dominant team could in theory continue an inning indefinitely."
Like in baseball, if a winning team wanted to, they could just keep the game going. It's not fun for the losers at all. Sure you can report them after but you still have to suffer through it. Sure you MIGHT be able to come back, but once games are that bad many people become demoralized and lose not because they are incapable of making a comeback, but because they no longer have the mindset that anything they do could possibly help them turn things around.
