I see what you mean. I think you should stick to one form and learn by difference or you could quickly get lost.
"ll" in standard spanish is a strong english "y".
However, in spanish argentinian from the area of Buenos Aires (but not the argentinian Córdoba, which sounds more like colombian spanish) it is "sh", being that s something like a mix in-between of "j" and "s" + h as in "she" but the sound is a bit different.
Without being able to record some sound I cannot express it better but I am sure you can find something around. Javier Milei, the president, has such an accent.
