Actual professors, no. Adjuncts. They don’t need ta’s for anything other than lab safety for the major-specific courses. It’s the first two years with the gobs and gobs of students.
TAs also grade quizzes, final exams, create questions for problems, etc... The professor often does very little work and leaves it to the TA, at least in my experience as a TA for physics courses. It's a lot more than just maintaining a lab.
