if you want to add information after placing order then you may use "checkout_onepage_controller_success_action" this event to add your custom data

You can get Gift message for order item using this code.

public function __construct(
    \Magento\GiftMessage\Api\OrderItemRepositoryInterface $orderItemGiftRepo
) {
    $this->orderItemGiftRepo = $orderItemGiftRepo;
}

public function getGiftMessage($orderId, $orderItemId)
{ 
    $giftMessage = $this->orderItemGiftRepo->get($orderId, $orderItemId);
    $giftMessage->getMessage(); // This will give you message
}

public function setGiftMessage($orderId)
{
 $giftMessage = $this->orderItemGiftRepo->get($orderId);
 $giftMessage->setMessage('custommessage'); 
}

Hope this will help you !!
