Do they connect to your network using credentials you supply?
• On Chrome OS versions 61–72, certificates added to an organizational unit are available to both network settings and kiosk apps on devices. On earlier versions, certificates are only available to the network settings on a device.

So far as I'm aware *all* modern operating systems don't allow the user to configure EAP-TTLS or PEAP. *All* systems refuse to accept even known CAs (i.e. web ones), unless the CA is enabled for EAP.
I suspect what's happening is that they Chrome devices are pulling the certificate information from your systems. So someone, somewhere, set it up for your network.

Yes... that *is* what I do about 10 times a day.

Yes, I'm not going to change my answer is you ask again.

No amount of additional FreeRADIUS logging will tell you what's going wrong with Windows.
In fact, if the client keeps trying EAP, the debug output will print out a huge warning, and point you to a Wiki page. That page describes exactly what's going wrong, and how to fix it.
Hint: configure Windows correctly.
