Again, not able to test, but I think this should work

import RPi.GPIO as GPIO
import time
from twilio.rest import Client
 
 
def send_sms(client, sms_text="Hello from Python!"):
    client.messages.create(to="+19732644152", 
                           from_="+12023351278", 
                           body=sms_text)
 
 
twilio_client = Client("ACxxxxxxxxxxxxxx", "zzzzzzzzzzzzz")
                            
GPIO.setmode(GPIO.BOARD)
GPIO.setwarnings(False)
GPIO.setup(7,GPIO.IN)   #LDR (Light Dependent Resistor)
 
GPIO.setup(11, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) #top switch
GPIO.setup(12, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) # bottom switch
 
GPIO.setup(15,GPIO.OUT) # Door Open
GPIO.setup(13,GPIO.OUT) # Door Close

# add events detection
GPIO.add_event_detect(7, GPIO.BOTH)
GPIO.add_event_detect(11, GPIO.RISING)
GPIO.add_event_detect(12, GPIO.RISING)

while True:
    if GPIO.event_detected(7) # change in light sensor
        if GPIO.input(7) == False and GPIO.input(11) == False: # it's day and door is not open
            print ("Day")
            print ("Open door")
            GPIO.output(15,True)
            print ("Start motor")
            print ("Current time %s"  % now )
        elif GPIO.input(7) == True and GPIO.input(12) == False: # it's night and door is not closed
            print ("Night")
            print ("Close door")
            GPIO.output(13,True) 
            print ("Drive motor")

    if GPIO.event_detected(11): # top switch change to HIGH
        GPIO.output(15,False)
        print ("STOP door open")
        send_sms(client=twilio_client, sms_text='Door open')
    
    if GPIO.event_detected(12): # bottom switch change to HIGH
        GPIO.output(13,False)
        print ("STOP door closed")
        send_sms(client=twilio_client, sms_text='Door closed')

Maybe it can be written better, but let's make it work as expected

not sure still looking at it but won't run getting invalid syntax looks like line 30

if GPIO.event_detected(7) # change in light sensor
