If God created everything, does that mean he created evil?

Evil is not something that can be created, evil is something that is brought upon someone in rebellion against a holy God. Satan was puffed up with pride and rebelled against God thus bringing evil upon himself.

You (Satan) said in your heart, “I will ascend to heaven; I will raise my throne above the stars of God, I will sit enthroned on the mount of assembly on the utmost heights of the sacred mountain. I will ascend above the tops of the clouds, I will make myself like the Most High”.

Isaiah 14:13-14

Just as Satan brought evil upon himself by his prideful desire to be like God. Eve (then Adam) brought evil to the human race by Eve’s desire.

When the woman saw that the fruit of the tree was good for food and pleasing to the eye and also desirable for gaining wisdom, she took some and ate it. She also gave some to her husband, who was with her, and he ate it.

Genesis 3:6

God did not bring sin into creation, our (through Adam) desires did. God did not trick or deceive Satan into becoming full of pride, Satan’s own desires caused his pride. And God does not tempt us to sin, it’s our own desires that entices us to sin.
