The distinction is in the understanding of what you are doing. “Script kiddie” is considered derogatory because running scripts written by someone else does not require understanding of how those scripts achieve what they do. It is a distinction between hacking a system and turning on a machine and standing nearby while it hacks the system.

Given that definition and distinction, using an AI model to do this is merely changing where the scripts came from. It may work, but the person doing it is still a “script kiddie” by the common definition.
