FWIW, here is what I would do.

After the sub was given to me and (before I accepted it) I noticed it would be illegal, I would inform the coach that the substitution would be illegal - he can't do it.
I can't imagine him insisting I make the substitution, BUT if she did,

Speaking ASA,

To start, lets note that there is no "illegal substitution" in ASA. You have an "unreported substitute" or an "illegal player".

At this point, you have already warned the coach that this substitution was a violation of the rules. If the coach then insisted on violating the rule after a warning, the game is over. (ASA 5.4.F) Extreme, absolutely. However, when you tell the coach that if s/he insist on making the change the game will be forfeited, most likely the issue would disappear.

I'd accept it. record it, announce it.

Then when I put the ball in play, I'd have to stop play and enforce the illegal player penalty.

Well, you cannot do that. If the violation is deemed that of an illegal player, this must be protested by the offended team. (ASA 4.6.E)
