I no longer work for the TLG, and I didn’t get to speak for the TLG when I did.
But while a lot of work over several years went into the TLG redaction of the 1940 LSJ (involving myself among others), that work involved proofreading, corrections to mistagging, typos or misprints in the digitisation (and very occasionally the source text), and updates to the hyperlinked citations. No substantive textual content was altered or added. The hyperlinks wouldn’t make sense in print, and the corrections over the source text really were slight. I don’t see an incentive for the TLG to do so, when the original LSJ is still in print.
The TLG Canon hasn’t been reprinted since 1990, and that represents original TLG work, which is updated and available online. If that has not been reprinted in book form, LSJ is far unlikelier still.
Again: I no longer work for the TLG, and I didn’t get to speak for the TLG when I did.
