“attacks a type of T Cell whose function it is to identify targets for the immune system.”
Would attacking thise type of T cell make the immune system less likely to also be able to identify and target infections?
That statement is wrong.

Your question is based on a false premise. As a general rule, most types of T cells, white blood cells also known as T lymphocytes, attack. The exception is T helper cells, IIRC.
I'm not an immunologist, but here's a section on CELL-MEDIATED IMMUNITY, the part that involves T cells. Humoral immunity involves B cells which generate antibodies. There's a fair amount of interplay between all the parts of the immune system, and plenty that's still not understood.
The link is from a med school immunology and microbiology course or courses. I took them as separate courses over 20 years ago.
