I have a directory filled with thousands of files in the format LastnameFirstnameYYYYMMDD.pdf. The last and first name will always been in title case.
I'd like to extract the last name so I can move these files to a directory structure of first letter of last name/lastname/full filename. Example: DoeJohn20190327 would be moved to D/Doe/DoeJohn20190327

Here you have a solution. I tested it an it creates the folders as you explained.
for filename in *.pdf
do
echo "Processing file $filename "
first_letter="$filename:0:1"
mkdir -p $first_letter #if already exists won't print error
last_name=$(echo $filename | sed 's/([^[:blank:]])([[:upper:]])/1 2/g' |awk 'print $1')
mkdir -p $first_letter/$last_name
mv $filename $first_letter/$last_name
done

If the lastname is always the shortest trailing string staring with an upper case letter (there are no compound lastnames for example) you could use a shell parameter expansion of the form $parameter%pattern
in place of a regex solution.
Ex.
for f in [[:upper:]]*[[:upper:]]*; do
d="$f:0:1/$f%[[:upper:]]*/"
echo mkdir -p "$d"
echo mv "$f" "$d"
done
mkdir -p D/Doe/
mv DoeJohn20190327 D/Doe/
Remove the echo
s when you are satisfied that it is doing the right thing.
