Glad that i have found an Answer which worked for me!

Changed the above code to,

$payouts = new \PayPal\Api\Payout();
            $senderBatchHeader = new \PayPal\Api\PayoutSenderBatchHeader();
            $senderBatchHeader->setSenderBatchId(uniqid().microtime(true))
                ->setEmailSubject("You have a payment");


                    $senderItem = new \PayPal\Api\PayoutItem();
                    $senderItem->setRecipientType('Email')
                        ->setNote('Thanks you.')
                        ->setReceiver('paypal_email@gmail.com')
                        ->setSenderItemId("item_1" . uniqid().microtime('true'))
                        ->setAmount(new \PayPal\Api\Currency('{
                    "value":"1.0",
                    "currency":"USD"
                }'));
                    $payouts->setSenderBatchHeader($senderBatchHeader)->addItem($senderItem);
            $request = clone $payouts;
            $apiContext = new \PayPal\Rest\ApiContext(
                new \PayPal\Auth\OAuthTokenCredential(
                    $paypal->client_id,
                    $paypal->client_secrete
                )
            );
            try {
                $output = $payouts->create(null, $apiContext);
            } catch (Exception $ex) {
            Flash::error(trans('payout.payout_error'));
                return redirect()->back();
            }
            Flash::success(trans('payout.payout_success'));
            return redirect()->back();
