What are the key steps needed to design an LLM-powered ad generator that creates unique ad copy for 10 million products while avoiding misleading claims?

1. Use grounded generation based on verified structured attributes. 2. Classify claims as factual or subjective for appropriate handling. 3. Verify factual claims against the database. 4. Handle superlatives as comparisons. 5. Use rule-based checks at scale and LLM judges for edge cases. 6. Apply extra scrutiny for regulated claims.
