Ahh I see.
No, that just the way the blockly GUI options work in that you have to drag the UI element to the virtual screen to access the functions.
Have you considered

Which then creates a hidden placeholder line which then give you access to the functions?
and then you create a function to create a line with a random colour.

Edit Ahh I see, UI line and lcd line have different color functions

Yes, but that only works if you drag a line to the screen and manually pre-define the placement and dimensions. You can then alter those later, but it's just the one line.

I want to programmatically draw multiple lines (via LCD.line) with random color(s) and there does not seem to be a Blockly way to achieve that (I'd prefer not to delve into executing Python code for this...)

I just checked and if you look at the attached image:

It is possible to set variable for the individual colours on a numerical value.
