Since you are asking this question, I will assume you know the lifespan of a dandelion. (If you do not, then it has a short life compared to other flowering plant species.) If the dandelion's only purpose is to send out its seeds and die, it has no need to use extra resources reinforcing its stem. The way it has its stem right now is a good enough stem to support the plant for its life. It does not need the material to make a full stem because it has a very simple goal. As long as it can transport the water and dissolved nutrients to the leaves, then it can carry out its purpose in life.

No, dandelions do not have spines. They are known for their bright yellow flowers and deeply lobed green leaves, which are typically smooth rather than spiny. The plant has a hollow stem and a taproot, but lacks any spiny structures.
the xylem cells in the stem are hollow so that the water & the minerals from the soil can be passed on to the leaf.

Dandelions are recognizable by their bright yellow flowers, which consist of numerous tiny petals arranged in a circular pattern. The leaves are deeply lobed and grow in a rosette at the base, while the stem is hollow and typically unbranched. After flowering, dandelions develop a spherical seed head composed of numerous white, fluffy seeds that can be easily dispersed by the wind. Their vibrant color and distinctive shape make them a common sight in gardens and meadows.

Because of it's hollow stem.
Bamboo comes from the stem of the bamboo plant, which is technically a type of grass. The stem is hollow and segmented, giving bamboo its distinctive appearance and strength.
The hollow stem of a lotus plant is called a "petiole." It is a leaf stalk that connects the leaf blade to the root system of the plant. The petiole helps provide support and transport nutrients and water throughout the plant.
