I just want an expert systems... Preferably as proper pages and not as chatbots. My last example was changing speed of my internet connection after an offer ended. For one reason or an other I had to use chat instead doing it myself on their website where they showed other stuff... No need to have LLM in loop, just cover these sort of basic cases with either clear pages or some flows...
