input: Write a function called `create_chatbot` that creates an AI-based chatbot in Python which answers simple queries about a product or service called XYZ. The function should return a dictionary containing possible questions and their pre-defined answers, and a function named `generate_response` that takes a question as input and returns the appropriate answer from the dictionary or a random message if the question is not found. If the user inputs 'Goodbye', the chatbot should terminate the conversation.
