I can't seem to find any currect production LF357's. I don't know if I am not looking properly or not. Are there any substitutes for this

If you don't need the high slew-rate (50V/usec) of the LF357, you can substitute it with the jelly-bean TL071, which has a slew rate of 13V/usec and a lower GBW product but is otherwise similar, for audio applications.
