Are there any moves that Smeargle cannot Sketch?

Question

I heard in some place that there is a move that he can't learn, I can't remember where... So is it true?

Smeargle can learn all moves, so don't get confused with the question.
What I'm asking is if Smeargle can't learn moves such as Explosion or suiciding moves.
Moves that attack multiple targets and OHKO no mather the level of Smeargle.
Like Roar makes the battle end.

Can Smeargle really learn any move by using Sketch?

Answer 1

In any generation:

• Blazing Torque
• Chatter
• Combat Torque
• Magical Torque
• Noxious Torque
• Revival Blessing
• Struggle
• Sketch
• Shadow moves
• Tera Starstorm
• Wicked Torque
• Z-Moves

In Generation II:

• Explosion
• Transform
• Metronome
• Mimic
• Mirror Move
• Selfdestruct
• Sleep Talk

In Generation IX:

• Dark Void
• Hyperspace Fury

In generations prior to Gen IX, Hyperspace Fury could be Sketched, but unable to be used in battle by a Pokemon other than Hoopa-Unbound. Starting in Generation VII, the same applies to Dark Void and Darkrai, and in Generation IX to Aura Wheel and Morpeko.

Sketch (Bulbapedia)

Bulbapedia says sketch can copy sleep talk in gen 3 onward.

Answer 2

The only moves that cannot be Sketched are Struggle and Chatter, as well as Shadow Moves.

Source, see the "Special Abilities" section.
