Will my bluebonnet die if the leaves curl?

Usually not, especially if it is just reacting to the heat. If pests are the cause, you just need to treat them quickly to save the foliage.

Should I water more if the leaves curl?

Only if the soil is completely dry. Bluebonnets hate wet feet, so overwatering can cause more damage than the heat itself.

Why are my Texas bluebonnet leaves curling? Causes and fixes

Check these first

Inspect the undersides of the leaves for small insects.
Feel the soil to see if it is bone dry or waterlogged.
Observe if the leaves uncurl when the sun goes down.

Likely causes

Aphid infestation
Most likely
How to tell: You will see clusters of tiny green or black insects on the undersides of leaves or on new growth. The leaves may look distorted or sticky from honeydew.
What to do: Spray the plant with a strong stream of water to knock them off. If they persist, use an insecticidal soap spray once a week until they are gone.
Heat stress
Possible
How to tell: The leaves curl inward during the hottest part of the day to conserve moisture. The plant usually looks better in the cool morning hours.
What to do: Ensure the soil is well drained so the roots do not sit in water. Provide a light layer of mulch around the base to keep the soil temperature steady.
