When you create LibreOffice documents and you want to send them to others, which may not be LibreOffice users, the normal procedure is to export your documents as PDF files, which ensures that anyone can use them.

Less frequently, you may want to export your documents to MS formats, if you want them to be editable, but that is much less foolproof than exporting to PDF.

I have worked for many years in companies where almost everybody was using MS Office, while I preferred to use LibreOffice (nowadays Excel remains better than any alternative, but I actually prefer LibreOffice Write to MS Word, because I think that the latter has regressed dramatically during the last 2 decades). Despite that, my coworkers were not even aware that I was using LibreOffice, as all the documentation generated by me was in PDF format.

Product documentation in any serious company should be in PDF format anyway, not in word processor formats that cannot be used by anyone who does not have an appropriate editor or viewer. Even using MS Office is not a guarantee that you can use any MS Office document file, as I have seen cases when recent MS Office versions could not open some ancient MS Office files, which could be opened by other tools, e.g. they could be imported in LibreOffice.

PDF is THE choice for cross-platform presentation and printing, but a real PITA for collaboration, funny enough one of the places where the web version of Word is pretty decent. A lot of industries live in Word/Office, and "generate PDF" is a pretty small part of their workflow. Also remember that printing to PDF without an expensive purchase was not a thing for many decades; I've only stopped using the Win2PDF license I bought 25 years ago on my most recent computers!
