Any help/suggestion is appreciated. Thank you.

You can use like this in list.phtml:-

$cart = $objectManager->get('\Magento\Checkout\Model\Session')->getQuote();
$result = $cart->getAllVisibleItems();
$itemsIds = array();
foreach ($result as $cartItem) {
    array_push($itemsIds, $cartItem->getProduct()->getId());
}

print_r(in_array($productId, $itemsIds));

As an alternative you can also use Magento default feature:-

For individual settings, go to product details

Click Advanced Inventory

Maximum allowed inventory, and make it 1

Can you please provide me the path to list.phtml?? – ratul keot Jan 18 '18 at 06:41
It is located here:-
vendor\magento\module-catalog\view\frontend\templates\product\list.phtml

But you will need to create a small module, and override it something like:-

app/design/frontend/Companyname/Module/Magento_Catalog/templates/product/list.phtml

I am using a theme. Will this effect because of that? – ratul keot Jan 18 '18 at 06:46
Logically you should do it by creating a theme of your own and making the theme which you are using as a parent theme. And hence change in that child theme. Such that in future is your theme gets updated this change does not get impacted. – dev_67Commerce Jan 18 '18 at 06:51

vendor\magento\module-catalog\view\frontend\templates\produc‌t\list.phtml

I think you should follow this thread, answer by @Marius
https://magento.stackexchange.com/questions/122287/how-to-create-simple-module-in-magento-2

You do not need to worry about controller in your case, composer.json, registration.php and module.xml should be sufficient for you and then once these 3 files are created, just copy paste your list.phtml from vendor into the path shared above of your module

You can check product exist or not in Quote by below code.

protected $checkoutSession;

public function __construct(
        \Magento\Checkout\Model\Session $checkoutSession
    )
    {
        $this->checkoutSession = $checkoutSession;
     }

$yourProductId = ''; //Add your product Id here

$this->checkoutSession->getQuote()->hasProductId($yourProductId);

You can use the hasProductId function to check if a product is available in the cart or not.
You should use the session factory to get the checkout session.

Don't use the objectManager directly. Use dependency injection.

private $checkoutSession;

public function __construct(
    \Magento\Checkout\Model\SessionFactory $checkoutSession
) {
    $this->checkoutSession = $checkoutSession;
}

.....
.....
$productId = "1"; // Add your product id

if ($this->checkoutSession->create()->getQuote()->hasProductId($productId)) {
    //product is available in the cart
}

}
