Exactly, this isn't a difficult problem to solve. If it's even a problem in the first place, because a sensible layout with good signage is enough for 99% of customers. A website to navigate a store is probably not even worth it in terms of net time savings, but it's convenient for customers and makes them more likely to go to your store if they can see something is in stock before they even leave their home, which is where the real return on investment is. An LLM can't give you live stock updates, so that's half of the value proposition gone.
