Answer 1

Try using the repository.

use Magento\Sales\Api\OrderItemRepositoryInterface;

/**
 * @var OrderItemRepositoryInterface
 */
private $orderItemRepository;


public function __construct(
    OrderItemRepositoryInterface $orderItemRepository
) {
    $this->orderItemRepository = $orderItemRepository;
}

Now:

$orderItem = $this->orderItemRepository->get(4);
error_log($orderItem->getName());
