Try it — you'll get something. Usually one page, with placeholder text about your commitment to excellence, no photos, and nothing telling Google what you do or where you work.
It builds what you ask for. Knowing what to ask for is most of the job: which pages you actually need, the cities you serve, the structured data that gets you into Google's local results, a form that reliably delivers, labels that let a screen reader use the page.
Then there's everything that isn't building at all — the domain, the host, the deploy, email that doesn't land in spam, Google and Bing registration, your business profile, monitoring so you find out before your customers do.
I use AI every day. It's part of why this costs $795 a month instead of $3,000. What you're paying for is someone who knows what to ask for, checks the answer against something real, and picks up the phone when it breaks.
