There are no GUI-less web browser available for Android

While I have not tried it recently, WebView at least used to have no particular requirement for displaying its UI. I used WebView from within a Service, in my case for a JavaScript interpreter (back before we had better options for that).

Now, an IntentService is not a good choice. WebView is largely asynchronous, and IntentService will destroy itself before WebView gets a chance to do its work. Use a regular Service, where you control the Service lifetime, so you can call stopSelf() only when you are ready to do so.

I want to use a WebView instance which can only run on an UI thread.

The relationship between WebView and threads is complicated. But, back when I last tried it, IIRC, a WebView that is not actually appearing on the screen did not need the main application thread. But, as I noted, WebView does most of its work asynchronously. You may find that you do not need a background thread of your own.

Is there a way to serialize the context of my activity so I can use this context to create my WebView?

No, nor would it address any of your concerns.

That is not possible, nor would it address any of your concerns.
