You can create a Batch Process and use the accessibility checker. In Acro 8 Pro the steps are: Advanced -> Document Processing -> Batch Processing -> New Sequence -> Type "accessibility checker" -> Select Command -> Double click Accessibility Checker.Set the Batch up to read the files or folder of files you are interested in.
When the file result says: 'All of the text in this document lacks a language specification' then there is text that is recognized in the document.
When the file result says: 'This document contains no fonts. If this document appears to contain text, it may be an image-only PDF file' then the file has no recognized text.
Yes, but instead of creating a Batch Process that requires interaction for every file read, I would count the words in the PDF and either create a report of the PDFs with zero words or print the list to the JS Console.

Hope this is helpful.
