Morphology
The core sense — lacking a reason or explanation — is directly recoverable from 'without' + 'reason', so a learner who knows those words would grasp most of the meaning. However, 'rhyme' is a metaphorical/intensifying element and the exact pairing is conventional and idiomatic, so full comprehension of the fixed phrase requires some exposure.
Etymology
Without rhyme or reason comes from an old idea that things can be ordered by rhyme (like a poem) or by reason (clear thinking). If something had neither, it felt messy or 'random', so today the phrase means 'with no logical explanation'.
