Lolth or Drow wouldn't have access to netherese magic as far as I am aware. The only race with access to this magic would be extraordinarily powerful elder archmages or the netherese. Powerful mages would have limited access to such magic though research etc. but enough to manipulate illithid tadpoles? Considering the netherese exploded their entire civilisation (4 small factions of netherese left apparently) trying to become gods I dunno.
On a sidenote wouldn't Drow who betrayed Lolth lose their red eyes? (blessing of Lolth).
