In order to decrypt a video, you need to have the key(s) that were used to encrypt it. The KID is just a key identifier, not the key itself. The key is usually not available (it is delivered using a DRM system), unless in special cases where an HLS .m3u8 file has a direct URL to a non-DRM-wrapped key (this would show as am #EXT-X-KEY line in the .m3u8 file).
