Morphology
The adjective 'lost' directly conveys confusion, but the segment 'at sea' is a metaphorical idiom whose meaning ('confused, unsure') is not fully predictable from the literal meanings of 'at' + 'sea'. Because the overall meaning can often be inferred (especially given 'lost') but relies on an idiomatic metaphorical phrase, the expression is partially transparent rather than fully compositional.
Etymology
The idiom lost and at sea comes from the image of a sailor on a ship with no land in sight and no clear way to steer, so they feel helpless and unsure where to go. That's why it now means 'feeling confused and unsure what to do'.
