Irrespective of this, removing the hello-authentication at the interface level doesn't resolve the issue with the key chain not authenticating.

I've not used key-chains, only the classical one-line config. But it
would seem like your IOS-XR is hmac-md5 (Safe) Junos is md5 (Unsafe).
Perhaps try to change IOS-XR to MD5 instead of HMAC-MD5.
