Why did mama (Isabella) tell Phil "they escaped safely"?


In episode 12 of The Promised Neverland. Isabella tells Phil, the smartest
among the 4 year olds, that the other kids escaped safely and he did not need
to worry. Did she know that Phil knows everything about the farm?

And if she did, did she suspect everyone below 4 years old?




She did suspect Phil but then after looking for the situation she concluded
that [the younger kids didn't know anything. (chapter
35).](https://i.stack.imgur.com/Ozqa6.png)

So why did she tell Phil everyone has escaped safely? That's because [she
already admitted her defeat (chapter
37),](https://i.stack.imgur.com/lXBan.png) and with that, she had nothing to
lose anymore.
