Need some input from a lawyer regarding car accident

Just a couple generic questions

Son ran into someone. He says they didn't have brake lights or no turn signal, nevertheless he hit her. His fault I get that. We just got served, lady is now suing my son (16) myself, and my wife. Saying he was intoxicated. Police report clearly states there was no alcohol involved.

I also have proof he wasn't on his phone.

My question, do we have any recourse for the false accusations? Being that this was filed and now it's public record any college scout could look for this and find it. Listen if he did it then I would tell him you screwed up but he didn't do anything except hit the lady. Now he says she didn't have brake lights and no turn signal but we have no dash cam to prove that so it is what it is. She told the officer that they worked before he hit her.

I'm just ticked about somebody just getting to say he was drunk when there was nothing of the sort happening, Even according to police and the hospital when he was taken
