It's a good thing that I work for Dick's Fish & Chips located on the main street of a bustling city in Antarctica. I wouldn't want the LLM to get it wrong.

Yup. The only difference between this and what any individual could already do is just time and scale.

Data brokers and government surveillance organizations have already had specialized tools to do this sort of thing for a while now, it's just that LLMs reduce the complexity and specialization needed to actually make an implementation that works well as an individual person.
