The customer role that the sales rep should meet with to address the concerns about a liability risk is legal. Legal is the customer role that is responsible for reviewing and approving the contractual terms and conditions, ensuring compliance with laws and regulations, and mitigating any potential risks or liabilities. The sales rep should consult with their own legal team and work collaboratively with the customer's legal team to resolve any issues or objections, and to finalize the agreement.
