I'll bite, Rob, does

LiquidCrystal_I2C lcd(0x27,2,1,0,4,5,6,7, BACKLIGHT_PIN, POSITIVE);

handle the init?

Apparantly the init() is a private member of the LiquidCrystal_I2C class so it cannot be called directly.

it is called by begin()

void LiquidCrystal_I2C::begin(uint8_t cols, uint8_t lines, uint8_t dotsize) 
{
   
   init();     // Initialise the I2C expander interface
   LCD::begin ( cols, lines, dotsize );   
}

a bit strange as it is the only place where init is called so the code could be transferred into begin()

Well you know that some programmers are compulsive about what they consider hard rules.
In this case, the only proper term is begin. Init is soooo last century. ;^)
