Morphology
The meaning is directly derivable from the constituents: 'insanity' (mental disturbance) + 'plea' (a formal legal claim) yields a plea based on insanity claiming lack of responsibility due to mental illness. This noun–noun/legal phrase pattern is transparent and cross-linguistically common, so a B1 learner who knows both words should be able to infer the MWE's meaning.
Etymology
Insanity plea is a phrase from the courtroom. A plea is a formal answer and insanity means a sick mind, so someone tells the court they were 'not responsible' for the crime because their mind was ill.
