I haven’t seen any errors and macOS seems to handle it greacefully. You can also disable it on macOS clients for network servers individually but that seems to be a loosing battle (even if you control all clients). They are finder settings after all

Thumbs.db files are created on my windows 11 pc at least. They’re only created for files that have metadata that requires reading those files. Explorer likes to display the metadata (sometimes) for some folders that have a lot of media in it (pictures, music, videos, etc). If the thumbs.db file is missing, windows will partially read every media file on the server to show thumbnails, that obviously creates unnecessary load but it’s really a trade off that might not make sense for most.
