The main issue with lead contamination in cast iron cookware is that people sometimes use it to melt lead for things like making bullets and fishing weights.
So in most cases griddles are probably pretty safe, they have a very shallow if any rim, so they’re not exactly ideal for holding a puddle of molten metal and pouring it into a mold. I’d be more concerned with pots and skillet that could hold liquid a little better.
That’s not to say there’s no risk though, I could certainly imagine someone using a griddle as a convenient heat-resistant surface to pour out leftover lead to cool on afterwards, but that’s probably significantly less common.
