Вот такая версия.

$links = [
    'Google' => [
            'Mail' => ['http://gmail.com', true, true],
            'Adwords' => ['http://google.com/adwords', true, false],
            'Adsense' => ['http://google.com/adwords', false, true]
    ],
    'Яндекс' => [
            'Метрика' => ['http://metrika.yandex.ru', false, false],
            'Direct' => ['http://direct.yandex.ru', true, true]
    ],
    'Yahoo' => ['http://yahoo.com', false, true],
    'Bing'  => ['https://bing.com', false, true]
];
//----------------------------------------------------------------

function attr_print($att1, $att2){
    $target = $att1 ?  "target='_blank'" : '';
    $nofollow = $att2 ? "rel='nofollow'" : '';
    return $target . " " . $nofollow;
}
// https://stackoverflow.com/a/173479
function isAssoc(array $arr)
{
    if (array() === $arr) return false;
    return array_keys($arr) !== range(0, count($arr) - 1);
}
//----------------------------------------------------------------
echo '<ul>';          
foreach( $links as $engine_name => $services ){
 $li = "<li>"; // Clear li
  if(isAssoc($services)){
      $li .=  $engine_name . '<ul>';
      foreach($services as $disc => $link){
        $li .=  '<li>';
        $li .= '<a href="' . $link[0] . '"';   
        $li .= attr_print($link[1], $link[2]);
        $li .= '>'; // Closing a
        $li .= $disc;
        $li .= '</a>';
        $li .= '</li>';
      }
       $li .= '</ul></li>';
    }else{ // Array ( [0] => http://yahoo.com [1] => false [2] => true ) regular
       $li .= '<a href="' . $services[0] . '" ';
       $li .= attr_print($services[1], $services[2]);

    }
    echo $li;
}

Если Я правильно понимаю, то должно все выглядеть как-то вот так.

$links = [
    'Google' => [
        'Mail' => ['http://gmail.com', true, true],
        'Adwords' => ['http://google.com/adwords', true, false],
        'Adsense' => ['http://google.com/adwords', false, true]
    ],
    'Яндекс' => [
        'Метрика' => ['http://metrika.yandex.ru', false, false],
        'Direct' => ['http://direct.yandex.ru', true, true]
    ],
    'Yahoo' => ['http://yahoo.com', false, true]
];
echo "<ul>";
foreach($links as $name=>$link) {
    echo "<li>";
    echo "$name";
    echo "<ul>";
    foreach($link as $item=>$value) {
       $blank = $value[1]==true ? "target='_blank'" : "";
       $nofollow = $value[2]==true ? "rel='nofollow'" ? "";
       echo "<li><a href='$value[0]' $blank $nofollow>$item</a></li>"
    }
    echo "</ul>";
    echo "</li>";
}
echo "</ul>";
