LLMs can code - different products. The plural of "It" is "They". Lol.

I didnt know, I am not native and have never seen it before

Like for example nobody says:

They cars can be fast.

People usually say:

The cars are fast.

Or sometimes:

Them cars are fast.

But never:

They cars are fast.

It's all good friend. I don't think I said "they LLMs" anywhere though? I think I just said "They can code .." etc.
