Macbook Pro 2013 - Unable to boot after attempting to remove Kali Linux partition

After attempting to remove a Kali Linux partition through Disk Utility on macOS High Sierra, I ended up with a drive that had a type of just FFFFFFF-FFFFF. I proceeded to try to fix that through using Internet Recovery, where I entered the following commands into Terminal:

gpt -r show disk0

diskutil umountDisk disk0

gpt remove -i 2 disk0

gpt add -i 2 -b 409640 -s 431203056 -t 7C3457EF-0000-11AA-AA11-00306543ECAC  disk0

This removed the partition type from being F, however, I am unsure if that led to the fact that I cannot access the drive's full storage. (I also somehow have 24 partitions...) I am now looking to reinstall macOS through Internet Recovery, but I cannot even mount my largest volume, disk0s2, which results in a fatal error. I have attached several photos of the situation, and unsure of what to do next. Please help!!
