In Jainism, devas and devis do exist, but they are not the ultimate controllers of death, love, food, or rain.

Core Jain view

• Life events happen mainly according to karma.
• No god creates, decides, or overrides karma.
• So death, attraction/love, food, and rain are not governed by a single divine manager in the Jain sense.

About specific tasks

• Death: not controlled by a Jain “god of death.” It happens when karmas mature.
• Love / attraction: not ruled by a deity in Jain doctrine; it arises from karmic causes and emotions.
• Food / nourishment: not provided by a special deity in the doctrinal sense; it comes through karmic fruition and worldly effort.
• Rain: some Jain traditions and folklore mention devas connected with weather or prosperity, but they are not absolute controllers of rain.

Important distinction

In Jain tradition, there are protective and attendant deities such as:

• Yakshas and Yakshinis
• Bhavanavasi, Vyantara, Jyotishka, and Vaimanika devas

These beings may be associated in popular devotion with protection, prosperity, auspiciousness, or help in worldly matters, but they do not run the universe and cannot cancel karma.

Short answer

Yes, Jain tradition has devas related to various worldly realms, but not as fixed gods of death, love, food, or rain. In Jainism, those things are ultimately governed by karma and natural causation, not by divine administration.

If you want, I can also give a Jain cosmology explanation of the types of devas.
