Re: "How can I keep my iPhone screen on during calls? assistive access mode for an elderly relative"
"Is there a way to have the screen stay "awake" continuously while the phone is receiving a call. Can't find anything in settings to fix this".
The screen goes blank in order to save battery power (eg: especially if no one is going to answer).
The auto-brightness feature may be on, and adjusting your display according to light conditions.
_____________
To turn auto-brightness on or off:
- In the Settings app, tap Accessibility.
- Tap Display & Text Size.
- Scroll to Auto-Brightness and tap to turn the feature on or off.

"To turn Always-On display off or on, follow these steps:
- In the Settings app, tap Display & Brightness.
- Scroll down to Always On Display and turn Always-On Display off or on".

Re: "The phone is the only function in assistive access mode. When receiving a call while the phone is locked the screen lights up with the call and the phone rings but the screen goes blank after a few seconds but phone continues to ring."
Apple Support's online article:
Make calls with Assistive Access on iPhone - Apple Support
says: "Answer a call : To answer an incoming call in Assistive Access, tap Answer.
If you don’t want to take the call, tap Don’t Answer, then tap Don’t Answer again to confirm.
If you turn on Show Notification Badges in Settings > Accessibility > Assistive Access, when the person using Assistive Access misses a call from a contact they’re allowed to call back, the Lock Screen and the Calls app show a notification icon. See Change Assistive Access settings."

Re: "In order to answer the call we have to touch the home button to wake-up the screen then answer".
Would it help your elderly relative to use Siri to answer (and / or hang. up) their calls?
Eg: There's a short third-party (non-Apple) video that explains how to set up and use that.
