list.phtml

Get the layout of Current Category

$yourCatId = $this->getCategoryId(); 
echo $this->getLayout()->getBlock('root')->getTemplate($yourCatId);

This is to get list of all category and there layouts:

$categories = Mage::getModel('catalog/category')->getCollection()
->addAttributeToSelect('id')
->addAttributeToSelect('name')
->addAttributeToSelect('url_key')
->addAttributeToSelect('url')
->addAttributeToSelect('is_active');

foreach ($categories as $category)
{
    if ($category->getIsActive()) { // Only pull Active categories
        $entity_id = $category->getId();
        echo $this->getLayout()->getBlock('root')->getTemplate($entity_id);

    }
}
