Has anyone ever tried to sue Hemingway for libel?

I just find it to be a funny contrast. With TSAR he was like "fuck it we ball" and wrote a thinly veiled roman à clef featuring unflattering depictions of his friends. Iirc, he even had everyone's real names in the first draft and later changed them. I think he pissed a few people off, but nobody actually brought legal action.

But then we have A Moveable Feast, where according to the new re-released edition, he wrote numerous different openings, which betray some serious concerns about being sued. But then he was growing increasingly paranoid at the time.

On a serious note, I did find that someone threatened a lawsuit over a portrayal in the Snows of Kilimanjaro, but it was something one of those stupid AI search summaries spat out and I couldn't find the actual source.

But yeah - given how often Hem wrote thinly veiled or composite portraits of people he really knew, you have to wonder. But maybe society was not as litigious back then?
