Nothing you describe hasn't already been done in the pre-LLM era with simple keyword matching. In the city i lived in 2012, the (now defunct) local supermarket chain could handle your roasted chicken request. You could also paste an entire grocery list into a text box and have it load the items into your cart all at once. That's the feature i moss the most. I just tried your snack and appetizers requests with the grocery service i currently use, and it worked fine. No "AI" needed.
