This pull request includes minor updates to the documentation for the BBS A.I. chatbot application in the website/pages/docs/llm/chat.mdx file. The changes focus on improving the clarity and accuracy of the language used to describe the capabilities and benefits of the A.I. chatbot.

Documentation improvements:

• Clarified the explanation of how TypeScript classes can be converted to A.I. chatbots and emphasized that GUI applications are no longer necessary in many cases.
• Updated the description of building A.I. chatbots with Swagger documents to highlight that GUI applications are less needed and that A.I. chatbots can efficiently replace many frontend developments.
