Time out and draw but the other side has enough material to mate

I guess since white only legal move is to take the queen then it will be not enough material to mate so it's a draw,

Seems like you already figured this out. Since it's impossible for black to deliver checkmate, it's a draw.

a draw by insuficcient material, but when you ran out of time it's not a draw.'

What cases are you talking about? If those are games which have been played after Lichess introduced
detection of (some) forced unwinnable positions (https://lichess.org/forum/lichess-feedback/i-played-a-game-in-which-i-won-but-it-was-called-a-draw) then they would be examples containing positions uncovered by the system.
One could check whether they result in a draw in case of a usual timeout.

6.9 Except where one of Articles 5.1.1, 5.1.2, 5.2.1, 5.2.2, 5.2.3 applies, if a player does not complete the prescribed number of moves in the allotted time, the game is lost by that player. However, the game is drawn if the position is such that the opponent cannot checkmate the player’s king by any possible series of legal moves.

(FIDE Laws of Chess, article 6.9)

It does not matter if 66. gxh4 has been played or not. What matters is whether there is a series of legal moves resulting in black checkmating white. In this case there clearly isn't as any legal continuation has to start with 66. gxh4 after which black has only a king and can no longer checkmate white. Therefore the result is a draw.

I think it's super clever of lichess to detect this kind of situation and handle it correctly
