Accessing value on the interface GraphQL\Language\AST\ValueNode suggest that you code against a concrete implementation. How about adding an instanceof check?

                    $renderable[$argName] = $argValue;
                }
                continue;
            }

            $validator = null;

The assignment to $validator is dead and can be removed.

            try {
                $validator = ValidatorFactory::class($name);
            } catch (ClassNotFoundException $e) {
                continue;
            }

            /**
             * @var ValidatorMetadata $metadata
             */
            $metadata = $validator::getMetadata();
            $arguments = [];

            foreach ($directive->arguments as $arg) {
                /**
                 * @var \GraphQL\Language\AST\ArgumentNode $arg
                 */

                $argName = $arg->name->value;
                $argValue = $arg->value->value; /** @phpstan-ignore-line */

                $argValidator = $metadata->argument($argName);
                if (!$argValidator) {
                    throw new Exception("Directive $validator does not have argument $argName");
                }
                if ($argValidator->type === 'Int') {
                    $argValue = (int)$argValue;
                }
                $arguments[$argName] = $argValue;
            }

            $validators[$name] = $arguments;
        }

        return new Field(
            $fieldName,
            $datatypeName,
            $renderable,
            $validators
