It might also help to get an age range of your daughter and budget.
My "go to" lens is a 24-105L but it is damned expensive and damned heavy and I wouldn't let a 17 year old near it unless they were a photography student never mind a 12 year old.
50mm 1.8 is you standard "first prime" lens and used to be about 100 quid but it doesn't give you anything more in zoom range than she has right now so unless the 15-45 is struggling with low light, motion blur or low quality it won't really deliver much. However if she's struggling to take steady picture of graffiti in dark alleyways then it might be worth a go - although the 15-45 that I can see at a quick google search has image stabilisation so might be OK in low light for static subjects like walls.
The budget zoom option would be the 75-300 as someone else mentioned - used to be bundled with cameras in a kit so often found 2nd hand once they have been superseded.
Another option - and possibly the best - would be some tuition on how to use an SLR but not sure how practical that is during lock-down.
