I mean sure, I'd certainly see that as problematic. Keep in mind we are also talking about two different levels of ethical issues - (1) CA paying for KM's attorneys, and (2) CA paying for KM's attorneys for the specific purpose that they effectively act in his interests and not hers, via instructions from his own attorney DOM (middle initial included to distinguish from the victim).
The latter scenario just seems really, really implausible to me given how absolutely, egregiously unethical that would be for all lawyers involved. It becomes especially implausible to me considering the particular lawyers involved, notably DOM who has a downright impeccable reputation.
The first scenario, CA paying for KM's attorneys but with no further implication re influence on the representation, certainly also presents issues. But you also have to assume there is zero chance that any such payments were made in such a direct way. As long as KM's lawyers are receiving payments that, upon due diligence, appear to legitimately be coming from her or her family, they are fine.
I think the first scenario is slightly more plausible than the second, and I also think that if it did occur, it was something the conspirators worked out among themselves and the lawyers are in the clear.
