It actually looks like setting those all to have public fixed all the errors, including the one with lldap. So, how can I get it to not put public there automatically for next time?
I assume you mean "get it to put public there" (i.e., the "not" is a typo)
You cannot. The security team has decided to not permit an opt-in bypass of the lock-downs implemented to fix CVE-2018-1058.
Your only real choice at the moment is to replace the function call in the generated expression with a custom function and in that custom function's create function command attach a "set search_path to public" clause. That will prevent inlining and also ensure the public schema is in the search_path when executing the public.ll_to_earth function call. With that in place the empty search_path in the dump file will no longer matter.
