"" is a legal object key in JSON and PHP just happens to be one
programming languages with full support of JSON, so why design JSON-LD
with focus on a particular choice of implementation in PHP? The language
can deal with "" keys in JSON data pretty well:
<?php
$json = '{"":1}';
$data = json_decode($json, true);
echo $data[""]; # prints '1'
?>
If you prefer PHP objects over PHP arrays, the "" can internally be
replaces by another special value but that's a personal choice of
implementation and out of the scope of JSON-LD.
Using "" for non-language strings looks like the cleanest and most
obvious solution to me.
Jakob
