Let me put it this way:

Samba isn't forwarding anything to sssd
Samba isn't doing your authentication, sssd is
Your windows clients are talking directly to sssd

This means you need to stop NTLMv1 from your Clients (I hope you
mean NTLMv1, because if you mean all NTLM versions there is a simple
solution, turn off your Windows machines.)

Whatever, this is not a Samba problem.
