Rotate the image the other way.

.circle {
  position: relative;
  background-color: #f5f5ff;
  border-radius: 50%;
  width: 400px;
  height: 400px;
  border: 2px solid black;
}

.tool {
  position: absolute;
  height: 100%;
  width: 100%;
  text-align: center;
  --rotation: 0;
  transform: rotate(var(--rotation));
  padding-top: 10px;
}

img {
  width: 75px;
  transform: rotate(calc(-1 * var(--rotation)));
  animation: spin 30s linear infinite reverse;
}

#css {
  --rotation: 0deg;
  --spin-initial: 0;
  animation: spin 30s linear infinite;
}

@keyframes spin {
  from {
    transform: rotate(calc(var(--spin-initial) * 1deg));
  }
  to {
    transform: rotate(calc(calc(360   var(--spin-initial)) * 1deg));
  }
}

Rotate the image inifintely in opposite direction of it's parent container to negate the rotation on image.
