As usual, differentiating the words themselves differentiates the concepts.
Therapy comes from the Greek therapeía, meaning "healing".
Tutoring comes from tutor and the Latin tutorem, meaning "guardian, watcher".
Therapy is designed to be a remedial, rehabilitating, or curative process. As such, it must be based on science. Language-literacy therapy involves using methods that have proven to normalize and remediate language processing difficulties.
Tutoring, on the other hand, is designed to assist a student in completing classwork assignments and/or preparing for exams. Thus, tutoring is not designed to improve the student's language-literacy processing but to help a student cope with academic demands.

Of course, improving language-processing skills usually results in improved academic performance.
