"I have a situation where a EGC will not fit on the neutral bar in the service equipment. I have tried to find a listed and same manufacturer add-on grounding lug kit to no avail.Except for the article 110 listing requirement issue is there anything wrong with installing a bolt-on lug of proper size and bolting it to the side of the panel with a nut and bolt? Code references please."
You did not mention specifics: manufacturer, wire size, panel...
I find it hard to believe that such a grounding lug is not made. Typically you have to look around in the catalog to find it. Give us more information and our crowd might know what you need off hand.
I know that all of the major brands have kits that cover the whole range of possibilities.
