What version are you on? 15? I'm on 14, and for me it's as it ever was. Also, can you replace it by editing the Shortcuts? I was able to replace the Internet thingy with separate toggles for Mobile Data/WiFi by doing that.
I'm on 14 but on a Pixel 8 and it's like OP shows now. Clicking the button on the quick menu just opens the screen OP is showing instead of turning off the BT radio like it did on my previous phone, which was also on Android 14.
For some reason, certain features and UI changes don't happen for every device even if they're on the same version of the OS. Like every phone maker has their own tweaked version of it for their specific phone, and it's not a universal experience for everyone just being on Android.
The "stock" rom offered by Google's own devices seems "enhanced" to the stock android given to any other device. But even between them, there are odd differences. My sister has a Pixel 7, just 1 iteration behind mine, and on the same OS version; but the UI isn't exactly the same. I can see special apps not being for hers, like Gemini (and even features of Gemini I do not have but the 8 Pro does); but for the basic settings menu and quick menu and shit to be different is weird as hell.
Yeah, dunno what Google's on. I've noticed that on my brothers pixel, it's not possible to deactivate the visual guide in the bottom of the screen for gesture navigation. The option just doesn't appear in his settings. It's all a bit silly.
