Welcome to the forum.

I have found the chords in the iRealPro app to be correct most of the time. You have to realize that users can upload songs of various accuracy, but the standards like this one are usually OK. In this case, "IReal first bar Dm7 Em7" is correct for the key of C.

I never heard of LJS so I looked at their website, but I would have to join to be able to see a chart. In this case, the first two chords could not be correct for any key of Autumn in New York. If the song were in F, it would start Gm7, Am7.

There are many standards available online for BIAB as well. Search for them using Google. A user, Notes Norton (nortonmusic.com) also offers fakebooks for sale of songs already in BIAB format.
