You aren't in breach of your RO. Forget what the LLM said. It is very likely that you used the wrong prompt. If you tell a LLM that you were away for 2.5 years and were in Canada only for 5 days, they'll say "yes, you'll be reported". But, when you factor in the 5 year rolling window, you get the real answer.
It is upto you on how convincing your plans for settlement is. I highly, highly doubt a s.44 can be issued to you:

^^ Read through 28(1).
Think of it in this way, would this being true changes anything for you? You'll still try to land, you'll still try to keep your PR intact. If you get questioned, just answer honestly. They are not out there to take your PR away from you, unless you do something to force them. You coming back to settle, your plans, etc matter <- that's for an almost impossible chance of s.44 being issued.
