The zip utility (of Info-ZIP) has the -F and -FF flags that should be able to
recover your files. Anyway, if you want to use LibreOffice for that, you could
use the attached Java code as a starting point. The key point in this code is
to explicitly set the input filter name, and the "RepairPackage" property to
true in the input MediaDescriptor.
