How to separate non-indented number points from indented number points?

Kyle:  Here's what I'd do (and this works if you want to try it):  Replace the hard returns between the main heading and its subparagraphs with a ~ followed by a # sign. That's a little laborious but you could speed it up with a macro. 

A paragraph with 2 subs would look like this:

You can also type a keyword to search online for the video that best fits your document. To make your document look professionally produced, Word provides header, footer, cover page, and text box designs that complement each other.~#For example, you can add a matching cover page, header, and sidebar. Click Insert and then choose the elements you want from the different galleries.~#Themes and styles also help keep your document coordinated. When you click Design and choose a new Theme, the pictures, charts, and SmartArt graphics change to match your new theme.

Then I'd sort the whole list; then I'd do a global search and replace to replace the ~ symbols with hard returns (^p) which will separate out all of the sub paragraphs.  I'd make sure the style I am using for the subparagraphs is a PARAGRAPH style and not a LINKED style.  Then I'd use Advanced Find to have word find and select all of the # in the document (you can select all in the main document).  That would highlight all of the # signs in the document that are sitting at the beginning of the subparagraphs.  Then I'd apply my paragraph style which would convert all of the paragraphs beginning with # to your sub levels with one click.  Then I'd replace the # signs with nothing to remove them (using the replace function).   If you have a linked style, it will only apply the style to the # signs which would accomplish nothing useful.  If you have a paragraph style, it'll apply to the entire paragraph even though you've only selected the # at the beginning of each subparagraph.
