comment Is sips lossless when used for JPEG rotation?
Yes, exactly. Also the rotation needs to be in a 90Deg increment. BUT -- your software needs to do it that way. Photoshop, Aperture, Automator, Preview, most other image editors or DAMs do NOT do it that way. They take the JPG file, uncompress to a common editable format (TIFF is common), perform whatever action, resave in the requested format which requires re-compression. Look at the link in my OP...

I think you misunderstood. The lossless JPEG rotation I am looking for does not uncompress or re-compress at all; rather it rotates the bit blocks so that the orientation changes with no change otherwise to the image. What you are suggesting is to resave the image at a lower compression, which does not solve the issue. Thanks tho!
