Is this suitable for university level

It depends. I know from experience that Open University maths exams do not allow calculators that can evaluate integrals so, in that case, this would not be allowed. I would ask the faculty what calculators are permissible in exams as this might also depend on the module, as well as the institution.

Does this calculator have a linear regression function?

Yes. A quick search on youtube for LG produced results. Good luck!

No this calculator does not have CAS. CAS stands for "Computer Algebra System", which means that calculators with this do symbolic algebra. This is why CAS calculators are banned in most exams.
