This will always be true
if ($logos = get_field("as_seen_on_logos", "options")):
true or false in this case is dependent of if a value is assigned to $logos and that will always happen even if the field has no value.
You need to get the value and then test the value, as far as I know you cannot do this all in the if, to test you can also display the value to make sure you’re getting what you expect.
$logos = get_field('as_seen_on_logos', 'options');
echo '<pre>'; var_dump($logos); echo '</pre>'; // test
if (!empty($logos)) {
// loop over logos
}
