Hi. There are some options here, don’t give up just yet.
The 1st and most obvious but expensive option is this analogue hearing aid:
Invisible Hearing Aids - Lyric | Phonak6
Lyric hearing aids are designed to remain out of sight and out of mind. Lyric is invisible in the ear canal and can be worn 24 hours per day, seven days a week for months at a time.
I have worn these. I have no eyesight I am totally blind, I also hate the sound of digital hearing aids. These aren’t suitable for me because of my hearing loss, but I can confirm they do sound amazing and they are invisible in the ear.
Your second option is the traditional behind the ear analogue hearing aids that are still being made here:

I’ve never used these, but they are quite cheap, you could give them a go.
Your next option are Widex. Widex hearing aids contain what they call Pure sound, or 0delay. This will take away that robotic sound called the comb effect that you don’t like. It honestly sounds quite like analogue. Not completely like analogue it’s true, but you will get a fairly good simulation.
The only thing about Widex, you will probably need custom ear molds as their feedback management is not that great. Even their non-Puresound programs are quite good, they only sound a little bit robotic.
I completely feel your pain on this issue it’s one that I hope will get better as processors get better, because the delay in processing sound goes away.
IN general, the more you can seal the ear, if you can stand to do this, the less robotic things wil sound because outside noise isn’t leaking in.
What I will say, whatever you do, avoid Oticons and Starkey hearing aids, as to my ears anyway, these sound the least analogue and the least natural. Widex or the newer Phonak Infinios sound quite nice. I’ve not tried Resound but you could try the vidia and see what you think.
Tell your audi to switch to a “music” program for best and most linniar results. Just understand that when people say linniar, it will probably still sound rubbish
