There is nothing in the Qt libraries for directly dealing with tar files or LZ4 compression. On the other hand, nothing in Qt stops you from linking libarchive (https://libarchive.org/) and the C code reference LZ4 implementation (https://lz4.github.io/lz4/) (there are certainly other options) or using QProcess to run standalone utilities to handle the files.
