I'm wondering if "lcd_string" should be "lcd.string" (per "lcd.message") 
  - would it be better to post the actual (not) working code?

Suggest you fire-up the Python REPR:

	python3		# on a Linux terminal

then:

	import ***whatever the LCD package is called ***
	help( ***whatever...called *** )

The output from this will tell you the names of all the entities within 
the package. Within that you will be able to check for the pertinent 
class (from which lcd was derived) and see what it says about arguments 
for the message() and/or string() methods - particularly the number of 
arguments and their data-type(s).
