This is something an LLM can do really well, really easily, with little engineering effort.

The cat is out of the bag. Most of us have a bunch of unstructured comment data that is peppered with references to local weather, policies, sports, etc. Determining what city or what district you live in is, sadly, not hard in this day and age.

This only requires a quick integration and some promo engineering. Assume people are already doing it.
