why is addCategory() a function of nlCategory when an instance of nlCategory is required to use the function.
$cat = $modx->newObject('nlCategory'); // I get instance
$cat->addCategory('Marketing Tools'); // use function on that instance

Because getting an instance to see if an instance already exists is wasteful IMO. If you wanted to use a static function on the class, that might be a better approach, then you avoid the unnecessary new instance if you are retrieving an existing instance from the database.

Why shouldn’t I do like that if it works?
$cat = $modx->newObject('nlCategory'); // I get instance $cat->addCategory('Marketing Tools'); // use function on that instance
<?php
$modx->loadClass('nlCategory');
$category = nlCategory::addCategory($name, $pid);
