Which RSA Key Exchange or/and RSA Signature algorithms do Openssl 1.1.1 use for ciphers AES256-GCM-SHA384 and ECDHE-RSA-CAMELLIA128-SHA256? Thanks.

RSA key exchange is defined in RFC2246:

This is of course independent of the OpenSSL version, and indeed of
OpenSSL, since it is a matter of TLS protocol interoperability and needs
to be compatible across all TLS 1.0–1.2 implementations.
