No, you do not become illegal once your card expires. You will remain a lawful permanent resident. That status can only be take from you through an order of removal, voluntary relinquishment, abandonment, or naturalization.
You simply won't have proof of your status.
Take me, for example. I'm a native born U.S. citizen. I have a birth certificate to prove it. If I lose my birth certificate, I don't lose my status, I just don't have a convenient way of showing it.
Same with you, right now. You're a green card holder with an expired green card. Your card expired, but your status didn't.
The date on the green card is just the date that the card itself expires. Your status as a permanent residnet does not end, you just can't rely on the old card for travel etc. This does not put your citizenship application in danger.
