I think str_in_list() is a good answer.

I was using it in action chains conditions where some variables can return empty values, so I had to nest the value in if statment to make sure it is not an empty string:

program:
	clicked_column = list_item(globals(_event_args), 1, ',');
	if clicked_column then
		if clicked_column inlist field_names('is_multiple:true,is_names:false') then
			'true'
		fi
	fi

Turns out there are other problems with the above code that I did not take into consideration: if variable is not anchored, #my_custom_col passes for #my_custom_col_1

Edit: The below code is working well

program:
	clicked_column = list_item(globals(_event_args), 1, ',');
	tag_like = field_names('is_multiple:true,is_names:false');
	str_in_list(tag_like, ',', clicked_column, 'true', '')
