NEC rules for a permanently installed pool

[Rjryan]

I gracefully bowed out of installing additional circuits for friends, because it got involved with a pool, reason being pool safety concerns. I understand now they are thinking about asking about these concerns.
Background: house built 2009, pool 2011 and house bought 2014
2 circuits involved 1. 2 pole breaker 20 amp 240 vac not GFCI
2. 1 single pole breaker 20 amp 120 vac not GFCI
Equipment: 2 pumps 240 vac, 2 timers 240 vac, Trumcell controller 240 vac, gas heater controls 240 vac
NEC 680.13 Maintenance disconnecting means, believe what's needed is a disconnecting means for the motor and timer controller for each motor
Disconnecting means for the Trumcell controller and a disconnect means for the heater controls.
NEC 680.5 (B) GFCI protection for the 2 pole 20 amp 240 vac breaker.
There are three other problems: added concrete on perimeter of pool extending it out from 1' to 3' for a small portion of the pool.
NEC 680.26(B)(2) Equipotential bonding extends 3' from pool perimeter, see no easy fix.
The patio next to the pool they have a 20 amp receptacle circuit tapped off the family room that is not GFCI less than 20' from pool.
NEC 680.22(A)(4) need to GFCI circuit.
Equipotential bonding wire smaller than #8.
NEC 680.26(B) #8 minimum bonding conductor, see no easy fix.
Don't know about single pool light, assume it is feed off the GFCI servicing receptacle and switched.

Any comments would be appreciate on the situation and are the NEC 2023 code articles correct.
