I suspect that if OpenAI didn't have ChatGPT continuously output these disclaimers then they could get in a lot of legal trouble if, say, someone asked it for medical or legal advice and then sued when something bad happened.
I sincerely hope OP is doing this for entertainment purposes only or as a very basic aid to shopping around, and not actually accepting medical advice from ChatGPT (or the Internet in general). The fact that I might be wrong about that suggests those disclaimers are absolutely necessary!
