Is it ok for a sister to attend online maths lessons taught by a male tutor if there’s others attending, not 1-to-1, and she doesn’t unmute or turn on her camera, and only types in the chat? The lessons are free and she’s working towards a maths qualification outside of this

Yes as long as it doesn't lead to fitnah and u need it and there is no alternative. But a female instructor takes precedence without a doubt and if this option is available then u should take this option rather than the male instructor.
