Why not Chief in command or Commander of chiefs or similar?
The sentence basically means Commander in biggest or Commander in most important. It’s a strange structure.
Commander in Chief actually goes back to the English Civil War (where Charles Howard was commissioned as lieutenant-general and commander-in-chief); and ‘in chief’ goes back to earlier french, basically denoting a feudal landholding that was given directly by the king.
Keep in mind that a Commander in Chief- while frequently the head of state; historically wasn’t always so. Colonial or Regional Governors were given command of military forces in their areas of authority- that is to say, commissioned as commanders with sole authority over all forces directly by the king. that is to say, they were commissioned as commanders in chief.
A lot of military rank terms derive from French. In French grammar, the noun modifier often goes after the thing it is modifying rather than before.

Origin of the title explains a lot.

Montréal, royal mountain
Montagne Russe, Rollercoaster (literally “Russian Mountain” because the first roller coasters were invented in Russia)
