Click on the LogisticRegression in the section you mentioned and you
will end up on the reference doc for this class where it is mentioned:

http://scikit-learn.org/stable/modules/generated/sklearn.linear_model.LogisticRegression.html#sklearn.linear_model.LogisticRegression

The multiclass doc also tells explicitly that all linear models (such
as LogisticRegression) are one-vs-all by default:
