You should only need to enable Samba with min SMBv2, max SMBv3 (the default) and with auto-sharing of USB drives turned on (the default). Modern Windows require SMB authentication so that needs to be on (not enabled by default).
If "Can play media from local Windows 11, Kodi app usb new volume." means the Kodi SMB client on a Windows Kodi install can play media from the LE Samba shares? .. the shares are working. The Kodi SMB client is different from the OS client (explorer, etc.).
Have you tried accessing via \\192.168.2.1 (or whatever the IP is) instead of \\LIBREELEC?
Option B .. use an SFTP client and transfer files over SSH instead.
