Hello, sorry to hear about this. I would not worry about this, but it does sound like he is harassing you. I would block/ignore him to the extent possible. When it comes to things like the permission/release from the kid, he has no standing to complain about that himself, so I would not worry there. If you have no reason to communicate with him and he continues to harass/threaten you then you can seek a restraining order to prevent the harassment (see for example, http://www.sdcourt.ca.gov/portal/page?_pageid=55,1554986&_dad=portal&_schema=PORTAL).
It is unlikely that they would have grounds to sue, let alone one that would be worthy of filing a lawsuit over. Also, any claims by them may be barred by the statute of limitations or equitable doctrine of laches....depending on the timing.
sure best of luck, most likely nothing will come of it
