There is any way to check if a directory is already symlinked, without

Please review "os — Miscellaneous operating system interfaces"
(https://docs.python.org/3/library/os.html)
- in particular os.stat() - and thus os.stat_result,
and given what you appear to be doing, possibly os.scandir() and
os.DirEntry.
I built a test:
dir1
-- dir-link = symlink to dir2
dir2
-- real-file
>>> os.stat( "dir2", follow_symlinks=True )
os.stat_result(st_mode=16893, st_ino=2345143, st_dev=64773, st_nlink=2,
st_uid=1000, st_gid=1000, st_size=4096, st_atime=1595793224,
st_mtime=1595793223, st_ctime=1595793223)
>>> os.stat( "dir1/dir-link", follow_symlinks=True )
os.stat_result(st_mode=16893, st_ino=2345143, st_dev=64773, st_nlink=2,
st_uid=1000, st_gid=1000, st_size=4096, st_atime=1595793224,
st_mtime=1595793223, st_ctime=1595793223)
>>> os.stat( "dir1/dir-link", follow_symlinks=False )
os.stat_result(st_mode=41471, st_ino=2345146, st_dev=64773, st_nlink=1,
st_uid=1000, st_gid=1000, st_size=7, st_atime=1595793558,
st_mtime=1595793558, st_ctime=1595793558)
NB st_size
Size of the file in bytes, if it is a regular file or a symbolic
link. The size of a symbolic link is the length of the pathname it
contains, without a terminating null byte.
Thus, compare the results of the two calls to detect a difference.
