I asked AI what is more - a million billion or a billion million

A million-billion and a billion-million are the same thing; both represent a million multiplied by a billion, or 10^12 + 10^9. This is equal to one trillion. Therefore, a million-billion is equal to a billion-million.

Does not seem right to me.
A trillion is 1000 x a billion, is this not true?

Apparently the terms "billion" and "trillion" can each have 2 definitions, depending on the naming scale system used. Billion can either mean 10^9 (short scale) or 10^12 (long scale). "Trillion" can mean 10^12 (short scale) or 10^18 (long scale).

Short scale calculations:
million billion: 10^6 * 10^9 = 10^15
billion million: 10^9 * 10^6 = 10^15

Long scale calculations:
million billion: 10^6 * 10^12 = 10^18
billion million: 10^12 * 10^6 = 10^18

So if AI said a million billion = a trillion, it's using the long scale naming system (10^18).

You are also correct that a trillion = 10^3 * 10*9 = 10^12, if using the short scale naming system.

(This though..."10^12 + 10^9"... I don't understand how AI used that to calculate a trillion. To me that 10^12 + 10^9 = 1,001,000,000,000 or 1.001 * 10^12).

@greencompass AI, eh? Who'd have it? It's only as good as the sources it trawls.
