'dual-led' originates from English, specifically the words 'dual' and 'led', where 'dual' comes from Latin 'dualis' (from 'duo') meaning 'two', and 'led' is the past participle form of 'lead' (Old English 'lǣdan') meaning 'to guide or bring'.

'dual' entered English via Latin/French influence (Latin 'dualis' from 'duo'), becoming Middle English 'dual'; 'led' developed as the past form of Old English 'lǣdan' (to lead), passing through Middle English forms before settling as Modern English 'lead' (past 'led').

Initially the components meant 'two' (for 'dual') and 'to guide/bring' (for 'lead'); combined in modern usage they form a compound meaning 'guided or directed by two (people or authorities)'.
