You should be able to put the root CA into the "certs" directory. And then OpenSSL will pick it up automatically.

PEAP is pretty much EAP-TLS plus MS-CHAP. MS-CHAP doesn't need the certs. EAP-TLS does.
There's a reason that the PEAP configuration references TLS. Because PEAP needs TLS.
And there's reason that the EAP-TLS configuration references TLS. And the certificates. Because EAP-TLS needs TLS.
