You can use the IOcrAutoRecognizeManager to get a searchable PDF using the following code:
static void OCR(string inputFile, string outputFile)
{
    using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD))
    {
        // Startup the LEADTOOLS OCR Engine
        ocrEngine.Startup(null, null, null, null);
        // Run the AutoRecognizeManager and specify PDF format
        ocrEngine.AutoRecognizeManager.Run(inputFile, outputFile, DocumentFormat.Pdf, null, null);
        Console.WriteLine($"OCR output saved to {outputFile}");
    }
}
