Answer 1

in list page you can use

if ($block->getMode() == 'grid') {
        $viewMode = 'grid';
        $image = 'category_page_grid';
        $showDescription = false;
        $templateType = \Magento\Catalog\Block\Product\ReviewRendererInterface::SHORT_VIEW;
    } else {
        $viewMode = 'list';
        $image = 'category_page_list';
        $showDescription = true;
        $templateType = \Magento\Catalog\Block\Product\ReviewRendererInterface::FULL_VIEW;
    }

<?php echo $block->getReviewsSummaryHtml($_product, $templateType); ?>

And Product Detail page You can use

echo $this->getLayout()->createBlock("Magento\Catalog\Block\Product\View")->setTemplate("Magento_Catalog::product/view/review.phtml")->toHtml();
