We do not like the fact that the new Divi 5 image module doesn't open the existing image in the media library, making it difficult to find and edit image properties quickly, particularly for large projects, adding hundreds of image alts would be overly time-consuming.

I have suggested a child theme modification and/or plug-in development.  See the linked instructions from ChatGPT for development suggestions and examples.
