Morphology
at + sea
The locative 'at' plus 'sea' creates a metaphorical image (being out on the sea suggests uncertainty or being lost), so there is a plausible connection to 'confused' but the exact idiomatic meaning is not directly derivable from the literal words. This metaphoric extension is somewhat inferable but not fully predictable for a B1 learner without prior exposure, so it is best classified as semi-transparent.
Etymology
At sea comes from sailors who were lost on the sea with no land in sight and did not know which way to go. So today at sea means 'confused' or 'not sure what to do'.
