>The amount of copying does not matter for a copyright claim.
This is incorrect. The amount of material used is the third factor in a fair use test. There are other ways it comes up as well (e.g. damage calculations).

> I'm not a lawyer but in the US, Copyright is a strict liability statute which means intent does not matter.
In this context, this is incorrect as well. People seem to be misinterpreting laws pretty badly, so instead of explaining how to apply here, I'll give a simpler, analogous context:

In this context, it depends on a lot of things, such as direct versus contributory infringement. This would likely be a contributory infringement case, where intent is almost a requirement. https://www.legalmatch.com/law-library/article/what-is-contr...
Keep in mind these are all factors. They matter, so they'll help swing a case one way or the other, but they're not something you can bank on in isolation. That's what will make for interesting case law.
