On iOS (iPod Touch 7) the Google option for default search engine fails
Search results page is blocked

Oh, pasting the URL into
opera.atlassian.net/servicedesk/customer/
linkified it to “Enable JavaScript to use search“
That wasn’t the title when I BookMarked the error page.
Un-linkified and chopped into key=value pairs:

In fact, it is almost as though Opera for iOS isn’t even supported by Opera!
No dedicated bug reporting.

That looks like a compatibility problem between the older Opera Touch/iOS build and Google Search.

The URL you posted is a normal Google Search URL. Google currently says Search works best with a supported, up-to-date version of Opera, while the old Opera Touch app is a separate product with its own search settings.

Since this is an iPod touch 7, I’d first check the iOS version and whether Opera can still be updated to its latest supported version. If the App Store won’t offer an update, try changing Opera’s default search engine to Bing or DuckDuckGo and see whether those work.

If only Google fails, I’d report this to Opera as a compatibility bug and include the exact Opera version, iOS version, and that same Google URL.
