AIBU to refuse my 17-year-old caring for a 14-year-old all week

My 17yo has a 14yo niece. He has been asked for look after her for a week whilst her family goes on holiday. She is no relation to me.
My 17yo is a good trustworthy guy, but i have yet to leave him alone in the house overnight. I think he would be absolutely fine, but the situation has never arisen.
I am however dead against him being responsible for a 14yo for a whole week. Maybe overnight with me on call. But not a whole week.
My mind is racing through worst case scenarios...missing 14yos, medical emergencies. household disasters, arguments etc.
I get that I would end up responsible for the 14yo as well.
I acknowledge that the law is unclear on this and relies on risk assessment and common sense. I wouldn't leave my 17yo alone for a week.
What does everyone else think?

i can’t get over the fact your 17yo has never been left alone for the night.

You haven’t listed the worst case scenarios. It would not be appropriate for a variety of reasons even allowing for him being a fabulous and capable human.

I wouldn’t. I can’t imagine either of them want that anyway.

Definitely not, maybe a weekend if they were siblings and sensible.
