The field "predictions" is an array will soon have several "description", if I understood what you want this should solve: 

<?php
$get = 'https://maps.googleapis.com/maps/api/place/autocomplete/json?&location=-18.866269,-41.9558537&radius=1&input=Rua%20Trin&types=address&language=pt_BR&key=dsdfdsfg21321erwr4rgf34gerg443g43hg34yh5t43tf3';

$VarJson = file_get_contents( $get );
$obj = json_decode($VarJson, true);
$VarRetorno = array_column($obj['predictions'], 'description');
echo implode("<br>", $VarRetorno);
?>

If you want only the first one you can change the array_column line to this: 

if(isset($obj['predictions'][0])){
    $VarRetorno = array_column($obj['predictions'][0], 'description');
}else{
    // seu tratamento
}
