The idea of children having access to a credit card strikes me as dangerous and irresponsible for many more reasons than just the odd chance that they use it to buy chemicals online.
If you want to buy something as a child, you use cash or get a parent's permission.

It's possible they have access to the credit card without permission. Most people don't keep their credit cards locked up in a gun safe.
Mine could be retrieved right now out of my wallet lying on a tray in my living room. I also don't have children, so I'm not particularly concerned personally. I haven't caught my dogs buying anything online yet.
If your kid can and will do things like steal your credit card, make unauthorized purchases and buy explosives.. the problem is not that William Osman didn't wear PPE.
I remember my own experience with "youtube explosives" as a kid.
I'd watched NurdRage's video [1] on how to extract lithium from a certain type of battery and thought that sounded like fun, so I asked my father to help me get the batteries needed. When he then asked me why I needed this specific type of (not cheap) battery, I showed him [1] and he said "That looks dangerous and fun, let's do it together" (or something to that effect).
One hour and some needle nose pliers later, we're down one battery and a burn hole in our bathroom tiles (as a result of a lithium fire that my father immediately suffocated), but up a bonding experience.
Had I tried to disassemble the battery alone (ignoring for a moment how I'd have gotten my hands on it in the first place without my father's knowledge, perhaps by stealing a credit card or with an Alexa's assistance, as other posters have suggested might happen), I probably would have attempted to extinguish the burning lithium by pouring water on it, which I'm sure would have gone excellently :).
I guess the moral of my story is that it's probably more effective to try to earn your kids' trust and ensure their safety yourself, rather than attempt to child-proof the rest of the world (with the assumption that your children will be going behind your back in their attempts to earn Darwin awards in new and exciting ways).
Stealing your parent's credit card strikes me as the more pressing issue here, rather than a youtube video that shows you how to do something dangerous.
