Sure, triage done by a human exist and they are generally absolved from taking that decision that could kill someone (to save others). Because the situation calls for it and would otherwise result in more deaths. But other than the situation calling for it, healthcare professionals are held to a certain standard and can be litigated against for medical malpractice.

That is not the case for ChatGPT apparently, and OpenAI should be held responsible for what their models do. They are very much aware of this because they did fine-tune GPT5 to avoid giving medical advice, even though it's still possible to work around.
