Хотя можно и так:
<p>Labas rytas!</p>
<div id="google_translate_element"></div>
<script>
function googleTranslateElementInit() {
new google.translate.TranslateElement({pageLanguage: 'lt'}, 'google_translate_element');
}
</script>
<script src="https://translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>
<script>
setTimeout(function(){
document.getElementsByTagName("select")[0].value="ru";
document.getElementsByTagName("select")[0].dispatchEvent(new Event('change'));
}, 1000);
</script>
</body>
</html>
