Depends on which COBOL they are using.

Latest standard is from 2023.

Nowadays everyone is moving into natural language programming, writing even longer prompts than COBOL applications.

That's quite the non sequitur. The relationship you mention isn't why COBOL is legacy.

I'm not in banking so I don't know if banks write new business logic with Cobol or merely maintain existing systems. I would be very surprised, though, if modern web-based products are using Cobol, or fancy high-speed trading platforms, or big data-driven machine learning, etc.
