Of course Lego is pronounced differently; English and Swedish are different languages. That the brand name Lego can be split into Swedish words does not make it a legitimate name.
Maybe your acquaintance is of the opinion that any "name" that has been used on a human (whether it's
Catherine,
John,
Bronwyn, Lego or Brfxxccxxmnpcccclllmmnprxvclmnckssqlbb11116) is a real, legitimate name.
ETA: Her dialect has nothing to do with whether Lego is a real name or not.
