Answer 1

You can try Following if your request builder is executing:

namespace Vendor\Module\Gateway\Payment\Request;

use Magento\Payment\Gateway\Request\BuilderInterface;
use Magento\Payment\Gateway\Helper\SubjectReader;

class Yourclass implements BuilderInterface
{

    public function build(array $buildSubject)
    {
        $paymentDO = SubjectReader::readPayment($buildSubject);

       $paymentInfo = $paymentDO->getPayment()  //this will give you  \Magento\Payment\Model\InfoInterface
    }
}

You refer above as example basically you need to use $paymentDO->getPayment() following code in your class as used in above.

Answer 2

I found an example of where an object of type \Magento\Payment\Model\InfoInterface can be found and how it is instantiated.

you may want to look at the file \Magento\Sales\Model\Order\Pdf\AbstractPdf

line $paymentInfo = $this->_paymentData->getInfoBlock($order->getPayment())->setIsSecureMode(true)->toPdf();

this line shows you how the invoice for an order is generated. This specific line extracts the payment information for the order. And the variable $order->getPayment() specifically is an object of type \Magento\Payment\Model\InfoInterface
