Tested the top 25 CSS files referenced in the rendered HTML. Files that return 404 are missing plugins (referenced CSS exists, but the plugin providing it isn't installed).

4 plugins have CSS referenced in the HTML but the plugin isn't installed:
Note: page builders often reference CSS for widgets the page doesn't actually use. So 404 on a CSS file doesn't necessarily mean the page looks broken — but it does mean the plugin is missing from disk.
