Why some twig templates have no file name suggestions
You can use the theme hook given to create your own theme hook / template suggestions or see additional suggestions that are not showing up in Twig debug, this happens occasionally. (I wonder if this is a bug?)

For example, the theme hook here you are targeting is views_view. 

If I do:

function MYTHEME_theme_suggestions_views_view_alter(&amp;$suggestions, $vars, $hook) {
  kint($vars);
}


... If the name of my view is "News" and it's a page display, I see in the theme area printed out in kint:



views_view__news__page_1
views_view__page_1
views_view__news__page
views_view__page
views_view__news


You can take any of these and replace the udnerscores with dashes and then add .html.twig and you should be good to go. 

e.g. views-view--news--page-1.html.twig
