There are times when I would ask for this. If it's midnight on a Saturday and the website says: "You can reach a human agent 9-5 M-F or we can have an AI agent call you right now" then I might opt for the AI agent. I may also do this if I want to take a call while out for a bike ride, in a noisy place, etc. Talking to AI means I don't need to worry about being polite which is actually very convenient.
