No, this isn't your fault.

I was using her laptop with Windows 7 while trying to upgrade to Windows 10. I checked the website to see if it was eligible, but it wasn’t. The system told me I needed an update key, which I didn’t have—so I canceled it. After turning it off and putting it back on, everything seemed fine until she called me saying the computer was too old for Windows 10. She mentioned she hadn’t used it since then. Was this my responsibility? I never really touched it, and it looked normal when I checked. How can I fix this? Thank you.
If you already have Windows 7, you shouldn't try to upgrade it to the newest version. Instead, use Windows Update to install the latest updates and service packs. The upgrade will simply move it to Pro or Ultimate, and you'll need a valid product key to complete the process.
It was indeed so, and she displayed numerous pop-ups that seemed like viruses.
It seems like you're checking if the laptop works again. Let me know what you found!
