Google will not provide the password of the user in cleartext, which is what you'd need for MS-CHAP to work. For MS-CHAP you need either the Cleartext-Password or the NT-Password (MD4ish(Cleartext-Password)) to be available on both the supplicant and the server.
You're pretty much limited to EAP-TTLS-PAP or PEAP-GTC. With those EAP methods you'd set control:Auth-Type := LDAP in the authorize section, and call the LDAP module again in the authenticate section.
This authenticates the user by submitting their cleartext credentials to Google's LDAP server as part of a Bind operation.
