LVM Filesystem recovery

I was trying to resize my LUKS crypt following this https://wiki.archlinux.org/index.php/Resizing_LVM-on-LUKS and I got to the partition resize with parted and seriously screwed things up. I typed 870 as the new size and forgot to put a G on the end. It shrunk my partition down to 870M I immediately resized it to 870G but by then the damage was done. Luckily I could still decrypt the LUKS crypt but I couldn't get my Logical Volume to even have a device file on the system. LVM recognized the volume as existing and showed the device file it was attached to but the file didn't exist and it showed it as having no filesystem. I did vgscan --mknodes and it successfully generated the device file but testdisk still wouldn't show it. I recreated the volume and put a new ext4 filesystem on it and now testdisk will show the drive but scanning yields nothing. I get a whole bunch of ext4 entries but all of them either say Can't open filesystem or No files found. Is there anyway for me to recover the filesystem that was on the disk? I don't want to write any data to it until I get what's on it off of it unless that's not possible.

EDIT: After poking around the real thing I need help with is recovering files from a previous ext4 filesystem. My drive had an ext4 system on it and that has since been overwritten with a new one however all the data from the old system still exists as shown by sudo dd if=/dev/Storage/Storage bs=1M | strings -fn 16. The only thing I did after my screw up was put a new ext4 FS on and nothing else so most of my data is probably still intact. I need to recover that data.

pvdisplay shows the following
