Does the AI make different decisions when it knows held items?

Question

I'm mostly asking about Frisk, but the answer probably applies to other item-revealing methods as well.

If a computer opponent had a Pokemon with Frisk and saw your Pokemon's item, would it impact the move it chooses? Some examples:

• Type-reducing berries (e.g. would a Chikorita with Tanga Berry still prompt Yanma to use Bug Buzz, or would it choose the now-stronger Air Slash?)
• Weakness Policy (would the computer stay away from using super effective moves?)
• Item-swapping moves (e.g. would a computer refuse to use Trick if it would give itself a harmful item like Black Sludge or Sticky Barb?)
• Conversely, would the computer prioritise Trick if it saw a helpful item like a Sitrus Berry?

I'd like an answer for the postgame battle facilities, but any other instances are welcome.

Thanks in advance.

How do you know this?

atp imma have to get my hands on an original catridge and try and reverse engineer the code or sm sht

Do you know the answer for other generations, like gen 5 or gen 6?

One more thing: trainers in gen 1 and maybe a few of the other older ones would have their Pokèmon use totally random moves.

There aren't held items in gen 1, and I don't believe there's any way to identify items in gen 2.
