function googleTranslateElementInit is for google translate widget to use so you must make it scope accessable. Which means you should have something like below:

mounted () {
  window.googleTranslateElementInit = function () {
    new google.translate.TranslateElement({pageLanguage: 'en', layout: google.translate.TranslateElement.InlineLayout.SIMPLE}, 'google_translate_element');
  }
},

Here is the sample snippet, it shows some cross origin error. But it does work on my local

new Vue({
  el: '#example',
  mounted () {
    window.googleTranslateElementInit = function () {
      new google.translate.TranslateElement({pageLanguage: 'en', layout: google.translate.TranslateElement.InlineLayout.SIMPLE}, 'google_translate_element');
    }
  }
})
