I disagree about your last statement. That only covers the initial creation/generation phase. It ignores the engineering aspect of maintaining that design through the entire lifecycle of the product. How do you evolve that table design?

Sure an LLM can update every table in your project every time you make a change, just as a human could. It also can make mistakes and burn significantly more tokens doing so. Or, it could update one component with a one line change and be done. Easy to verify, less change for mistakes.

Engineering is a discipline and does not change dramatically with the advent of outsourcing it to agents.
