so when you’re on Chrome you can login to your Google account to save and sync browser data
Is there any way that a site can use Javascript code to detect that? Or even call a library to detect it?

A very good W3school tutorial can be found here.

No. It would be a massive security/privacy issue.
(Granted, the web has had those before, but if this were one, it would have been closed by now.)
No, like mentioned in the answer here.
But maybe good to mention that it’s possible the other way around: Your Chrome browser can detect that the 3rd party site (or app) you are visiting supports login with Chrome and could show a Google account sign in prompt.
Read here for more details on that feature.
This prompting feature can be disabled here.
