In my experience, all tests from https://pagespeed.web.dev/ use the Chrome-Lighthouse substring to identify as bot.

Examples:

• Mozilla/5.0 (Linux; Android 7.0; Moto G (4)) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4590.2 Mobile Safari/537.36 Chrome-Lighthouse
• Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4590.2 Safari/537.36 Chrome-Lighthouse

Check example on isbot.js.org

Any way, you refer to the README clarifications:

What does "isbot" do?

This package aims to identify "Good bots". Those who voluntarily identify themselves by setting a unique, preferably descriptive, user agent, usually by setting a dedicated request header.

What doesn't "isbot" do?

It does not try to recognise malicious bots or programs disguising themselves as real users.

If a tool uses legitimate browser user agent string with no indication of being an automated service - we can not use this tool to identify it.

Continuing in clarifications section:

...other methods of identification can be added such as reverse dns lookup.

I can see Pagespeed have decided to not recognise themselves as a bot using the user agent string. Also mentioned in discussion #214
