If you want to view it that way, sure, I won't disagree.
But L&T having that problem also contributes to the problems of the MCU at large, where each movie has to be some "villain of the week" that's introduced at the start of the movie and disposed of at the end, with a chance of a tease that the villain may return or perhaps a hint of some larger threat; either of which may ultimately lead nowhere. Up to to Infinity War, they were pretty good about those hints of a large threat, obviously with Infinity War and Endgame paying that off. Since then... What have we actually got? They seem to have finally settled on a new major arc, until some real life drama may have derailed that (maybe Deadpool & Wolverine will advance that plot? idk)
At least in retrospect, I think L&T could have been a more interesting movie if it had completely eschewed the villain a-plot and focused either more or completely on the Jane b-plot. Christian Bale's villain could have made for a really good ~3 movie arc, though, either beginning or ending in L&T. But yeah, the Taika Waititi humor really didn't mesh well with either a- or b-plot.
I think Endgame itself was really the beginning of the current MCU problem. They were in too much of a rush to conclude the Thanos story. Where that movie started with a scripted five year gap, we should have had that five year gap for real. Let us feel the consequences of the Snap the way the characters did. Give us the Hawkeye/Ronin and Black Widow movies (amongst others) that show everyone dealing with the catastrophe. Let the consequences of their failure to stop Thanos really hit home. (And while I'm typing all this, please conclude that story without time travel, but that's an entirely separate rant, lol.)
