My brother gave me some lens meant for his T70 film camera. I have a Canon Rebel T7. I know it needs an FD to EOS adapter with optical lens.
Can anyone suggest one that won’t degrade the picture too much?

Hi @smodette it’s not worth your time adapting FD lenses to the EF Mount. All adapters with optical correction result in a 1.26x teleconverter and no focus to infinity. There will also be no kind of automation like EF lenses have. Also it will difficult to manually focus the lens. Since the viewfinder has no focus aids like a split prism or micro prism. The optical quality of FD lenses won’t match any EF lenses including older ones.

"too much" is wholly subjective. Most, but not all, people do not hate the Vello version for just $29 on B&H. That seems a reasonable first choice, then you can decide if it is "too much" degradation and also decide if you still want to use the lens despite all of the shortcomings that deebatman316 has pointed out to you. the K&F version is 4.4 stars on Amazon for $37
I have no hands-on experience with either and cannot recommend them personally, but it seems that given deebatman316's input you should not make a big investment into this solution.

If I choose to move forward anyway, is there an adapter you would recommend?

I am not comfortable making recommendations for products that I've never used. If nobody here offers you a recommendation I can wholeheartedly endorse B&H and suggest that you give them a call and purchase from them. They are extremely knowledgeable and professional.

I reached out to a buddy who loves working with older and odd cameras and he has the K&F adapter and is happy with the functionality.
My first "real" camera was a Canon AE-1 so I grew up with manual focus but many people hate manual focus and it will be more difficult without the focusing screen that provided the split image "bubble". But if you have good eyesight, you will quickly master focusing via close inspection of the viewfinder and unless you are using wide aperture telephoto lenses wide open, you have a bit of leeway in focus precision.
At under $40, the K&F Concepts adapter is a cheap experiment and will let you experiment with the FD glass. Certainly lense design has gotten better BUT a lot of great photos were captured back in the day using FD series lenses so you should still be able to find some use for them. Modern photography is less dependent upon the skill of the photographer in many ways so it is easier to get garbage shots with vintage camera gear BUT I can assure you I have succeeded in getting more than one garbage shot with my 1DX III bodies using Canon L series primes that cost in the five figure range 🤣
Have fun with your newly gifted glass!
