It seems like initializeIfNotInitialized() must be provided by classes using this trait. How about adding it as abstract method to this trait?

        return $this->getRenderer()->render();
    }

    public function getRenderer()

        if (!$this->_renderer) {
            $this->initializeIfNotInitialized();
            $this->_renderer = $this->getNewRenderer();
        }

        return $this->_renderer;
    }
