There is documentation about message passing on a Chrome extension

as well as a few Stack Overflow links on how to check whether a user has a Chrome extension installed from a web page

But, I've been doing some research and I haven't found a definite answer on whether a Chrome extension (or even a web page) can tell if a Google add-on is installed or not. I was hoping add-ons would have the same message passing option extensions have, but it doesn't look like to be the case. If not, any potential workarounds?

By reading your question, What I understand is, you want to know if a particular extension like is installed or not in your browser.

If that is the question then, yes we can get that details using chrome extension, Follow these steps, First

  • Add management permission in your manifest.json file.

Second

  • Use chrome API of management which gives you details of all installed extensions
  • I used the API on extension click.
chrome.browserAction.onClicked.addListener(() => {
    chrome.management.getAll((allExtension) => {
        console.log('allExtension: ', allExtension);
    });
});

Reference

I hope, I gave you the right answer.
