If you claim your company or as an individual providing service to public you do not have to teach the student and/ or provide and exam. If you claim to be ADA compliant it is a different story and then you have to provide the test in braille or oral format. As far as the shooting test goes I don't think there is a guideline at ADA (see hhtps://www.ada.gov).
I am legally blind, obtained my CHL long before I had a complete vision loss due to west Nile fever and the side effects of it in 2012. All doctors said my eyesight will not return because of the damage done to the optical nerves. I had 105 deg F fever for over 6 days, menegitis and encyphalitis which caused vision loss, 60 pound weight loss in 6 days and a series of other symptoms.
At the beginning of 2013 I retained a minor spot of vision in my left eye which gradualy improved over the years and as of today I can do almost everything required for an autonomous live with the exception of driving in public but that may work as well sometimes in the future.
When I was determined disabled I received the status "long term disability" not permanent disabled.
I also renewed my DL and LTC once since I had my vision loss. I went to the range after 2 years for the first time and have no issue passing the minimum score if ambient lighting permits.
I am also aware of the law, do not carry in public to avoid any problems with the law but given the fact my vision is still improving I renewed anyway.
In regards to home defense, I have homogenous lighting throughout my home in order to acomodaste for my vision. My primary alarm system comes on 4 legs and he won't miss anything suspicious.
In regards to a completely blind person I would not recomand a gun at all. I went through that state and all I can say is that I had a problem finding the restroom on time until I learned how to deal with about anything without vision at all. If that blind person needs protection I'd suggest a dog.
To the subject again:
If that person needs help he is welcome to contact me via P.M. on this forum, I have some good experience and knowledge how to improve a humans vision. I learned swimming because I was thrown in the pond.
