The notes for the DuoLingo French course claim that an intransitive verb, in French, can take an indirect object:
In "Je parle à Jacques", is "parler" an intransitive verb, and "à Jacques" indirect object (introduced by à) ?

Duolingo's last statement is self-contradictory. By definition, intransitive verbs can't have compléments d'objets.
The confusion might be due to the fact many verbs can be used either in a transitive or an intransitive way. Transitivity is more about defining their usage than some intrinsic quality of a verb. Only a subset of verbs are exclusively of one kind or another, e.g. dormir is exclusively intransitive.
On the other hand, parler can be used either as an intransitive, transitive direct or transitive indirect verb.
