Honestly, a part of me wonders if Disney+ is basing its placement for Love & Thunder on when Korg is telling the story rather than the events within the said story. The same thing could be theorized with Iron Man 3 being set after The Dark World due to Tony telling the story to Bruce at a time past the events of The Dark World. In both cases, the movies are technically recapping actual events rather than us seeing them in "real-time". Not saying this is exactly what's going on and if it were the case, it'd be nice to see clarification, but I could see it making sense.
