That "list with largish thumbnails" of products is just a "design issue".
You can see that every-other theme tries different aproaches for that list/view.
That means, you can also modify/customize the look as you want by changing the CSS-styles as you want.
In the extensions page for Woocommerce,
there is an extension for such a functionality:
WooCommerce Grid / List toggle
You can check it for yourself, it is free:
