UPDATE: I was able to figure out a solution!
I was able to go into the Yomitan’s Anki card generating code and strip out the parts that were generating the definitions as an ordered list. I honestly should have just tried a little harder lol, but after realizing you can look at fields as if they were in a HTML editor, I was able better cross reference the exact Yomitan code responsible for generating the ordered list and modify it.
<ol>{{#each definition.glossary}}<li>{{.}}</li>{{/each}}</ol>
Turned into:
{{#each definition.glossary}}{{.}}, {{/each}}
This allowed type-answer to process it as one big chunk of text instead, including the ", " I made it put after every item in the ordered list it came from, instead of individual items that were then smushed together after processing. It makes it look so much better and easier to read. It now looks like this:
