We are currently pulling data via the API to look various metrics, including reviews and ratings. However, I noticed the ratings only come in with associated reviews - it doesn't appear there is public access to the API for pulling all historic ratings (without associated reviews).
Is this correct? Does anyone know a workaround or way to access the ratings data via API or other method?
I assume you're using this collection of APIs. The name is 'review' not 'rating' so that is the gap.
Make a feedback, reference mine in it. I would want this capability too.

FB21900768 - App Store Connect API: Make a collection of APIs for retrieving app ratings - or enrich the review API to allow fetching ratings without requring the user to have left a review for deeper user sentiment analysis
The App Store Connect API doesn't expose standalone ratings (without reviews), but you can get aggregate ratings data through the App Analytics reports. Specifically, the Analytics Reports API lets you request report types like APP_STORE_ENGAGEMENT which includes ratings counts. You can also use the legacy Reporter tool (java -jar Reporter.jar) to download Sales and Trends reports that include ratings metrics. It's not as clean as a direct REST endpoint for individual ratings, but it should give you the historical data you're looking for.
