Here is a link for how to prevent the LM hash from being stored:

This seems to me to be what you suspected.  In Type3Message.java at
the bottom there is this:

// NTLMv2 issues w/cross-domain authentication; leave NT empty if >= 3
if (LM_COMPATIBILITY < 3) setNTResponse(ntResponse);

You could try to edit this and see if it works to fix it.
