While I'm not familiar with LibreOffice, you can try using the DocumentConverter to convert the files to PDF. This supports many file formats. Here is the code you can try:
using (DocumentConverter documentConverter = new DocumentConverter())
{
   var inFile = @"C:\Input\input.docx");
   var outFile = @"C:\Output\output.pdf");
   var jobData = DocumentConverterJobs.CreateJobData(inFile, outFile, DocumentFormat.Pdf);
   jobData.JobName = "conversion job";

   var documentWriter = new DocumentWriter();
   documentConverter.SetDocumentWriterInstance(documentWriter);

   var renderingEngine = new AnnWinFormsRenderingEngine();
   documentConverter.SetAnnRenderingEngineInstance(renderingEngine);

   var job = documentConverter.Jobs.CreateJob(jobData);
   documentConverter.Jobs.RunJob(job);
}

You can use itextsharp nuget to create pdf. It's free.

Hi,

You can also use Spire.Office to convert files like word, excel, powerpoint, image,html and text etc. to pdf.

In this attachement Apart from concole there's one self host service you just install that service and it works like a localhost url so you just need to call that url whenever you want to convert it into pdf

Check attached zip file
There's one console application
you can check the code for your reference
In that Console inside program.cs there's method

public static string getLibreOfficePath()
{
switch (Environment.OSVersion.Platform)
{
case PlatformID.Unix:
return "/usr/bin/soffice";
case PlatformID.Win32NT:
return AppDomain.CurrentDomain.BaseDirectory + @"\Windows\program\soffice.exe";
default:
throw new PlatformNotSupportedException("Your OS is not supported");
}
}

In this method you need set soffice.exe path of your machine like
(The soffice.exe file is located in a subfolder of "C:\Program Files (x86)" (typically C:\Program Files (x86)\OpenOffice.org 3\program\ or C:\Program Files (x86)\OpenOffice 4\program\))
