Before you dump the MS Office grammar checker, you might want to test the LanguageTool grammar checker to make sure it's good enough for your purposes. (You can test it online.)

What I like about it, is that adding new rules doesn't require programming skills or a linguistics degree, because the developers have created a very user-friendly online rule editor.
For example, the following rule will check for words with numbers in them:

        title="Easy editing stylesheet" ?>

<!-- English user rules -->

<rules lang="en" xsi:noNamespaceSchemaLocation="../../../../../../../../../languagetool-core/src/main/resources/org/languagetool/rules/rules.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <category id="GRAMMAR" name="Grammar" type="grammar">
<!-- list of EN POS tags: https://github.com/languagetool-org/languagetool/blob/master/languagetool-language-modules/de/src/main/resources/org/languagetool/resource/en/tagset.txt -->
    
    <!-- start of custom rule #1 -->
  <category id="GRAMMAR" name="Grammar" type="grammar">
    <!-- start of custom rule -->
    <rule id="GG_RULE_1" name="word contains numbers">
     <pattern>
      <token regexp="yes">\w*\d\w*</token>
     </pattern>
     <message>This word contains numbers and letters.</message>
     <short>Possible OCR error</short>
    </rule>
    <!-- end of custom rule -->
  </category>
    <!-- end of custom rule -->
      
  </category>
</rules>

(For your convenience I've attached the rule file. Once you've installed the LanguageTool plugin, unzip the .xml file and copy it to the LanguageTool plugin folder to activate it.)

LibreOffice only comes with a very limited grammar checker. You'll need to download the LanguageTool OXT file and install it via Tools > Extension Manager. (If you encounter problems read the LanguageTool troubleshooting guide.)
