The "libby in the mental institution" bit was most likely a leftover from (or homage to) one of the original ideas for the series, which was that the entire show took place in Hurley's mind.
iirc Jack was to be Hurley's real life physician in that scenario.
I never liked that theory. To be honest I think the “they’re all in purgatory” ending was the best way to go.
If the writers weren’t forced to extend the show with, IMHO, unnecessary seasons 4 and bits of 5 then the ending and the series as a whole would’ve been much better.
