Well - since this line works
$this->getVars = t3lib_div::_GET();
class.t3lib_div.php should be available.

And I already got a working function call with:
$labels = $GLOBALS['TSFE']->readLLfile('EXT:locallang_db.php');

But there must still be something wrong with the syntax for the file/path
since the result is an empty array although there is something defined in
locallang_db.php
